Electric Fence Monitor-  A Very Efficient and Simple CMOS Design. __ Designed by G.L. Chemelec

Electric Fence project-  A Very Efficient and Simple CMOS Design __ Designed by G.L. Chemelec

Electric Fence project Fencer-1-  A Very Efficient and Simple CMOS Design.  This is the Second Most Popular Project on my site.  Look and See What one of this circuit Caught? __ Designed by G.L. Chemelec

Electric Fence project Fencer-2-  Considerably MORE POWERFUL, If Needed!.  This is the Third Most Popular Project on my site. __ Designed by G.L. Chemelec

Electronic Dazer-  The dazer is considered an illegal firearm in Canada, except for use by speciality forces and law enforcement.  Unless for laboratory experimentation, having it in your possession is the same as having an illegal gun or a gun without the proper FAC permits.  It is presented here for educational and experimental purposes only as part of our High-Voltage Projects. __ Designed by Tony van Roon  VA3AVR

Even Cheaper & Simpler Ion Chamber-  Here is a really simple version of the above chamber that is surprisingly sensitive for its simplicity.  It uses the same coffee can as above but only one transistor.  Here are step-by-step instructions for constructing this really easy-to-build version. __ Contact:  Charles Wenzel of Wenzel Associates, Inc.

Experimenter's Chamber-  This experimenter's chamber is made from a 4" (10 cm) diameter, 5.5" (14 cm) tall tin with a tight-fitting lid.  A 5-way binding post is mounted in the center of the can and a 4" (10 cm) wire is suspended from the post inside the can.  The wire length is short enough to insure that it doesn't touch the lid.  Another all-metal binding post and pin are installed in the bottom of the can, and a sheet of gray insulating plastic is glued into place to keep hastily constructed experiments from contacting the can.  The electrometer circuitry will be extremely sensitive to stray electric fields, so a shield is mandatory.  Another can previously containing mints is pressed into service __ Contact:  Charles Wenzel of Wenzel Associates, Inc.

Flyback Transformer Driver-  This is by far the best project for someone who is already familiar with High Voltage, but wants to take their experiments to the next level: It requires very little previous experience and skills with soldering and identifying components, and there are virtually no adjustments to be made.  The danger is minimal, as fly back transformers are intrinsically low power devices, not capable of outputting lethal currents (due to the hair-thin secondary windings) , and yet it will give a careless experimenter a nasty RF burn if he accidentally touches the HV wire (nothing beats learning from your mistakes).  If you have never experimented with HV before though, I recommend you start off with an electrostatic project.  This circuit is not a toy! __ Contact Sam Barros

Flyback Transformer Drivers-  This page contains all of the flyback drivers I have tested.  From petty 5V drivers to direct mains driven.__

Fres Finder-  Easy method for finding Tesla Coil resonances.__

GK-71 High Frequency Vacuum Tube Tesla Coil-  Hot, high frequency plasma with a vacuum tube.__

HeNe Laser Power Supply-  If you have ever worked with lasers, you know how fun and interesting it can be, you also know how expensive it can be.  The high voltage power supplies for the laser tubes are often more expensive then the tubes themselves.  This supply can be built with commmon parts, most of which you probably already have in your junk box.  The secret is the transformer used.  It is a common 9V 1A unit, connected backwards for step up __ Designed by Aaron Cake

High & Low Voltage Cut Off with Time Delay-  The power line fluctuations and cut-offs cause damages to electrical appliances connected to the line.  It is more serious in the case of domestic appliances like fridge and air conditioners.  If a fridge is operated on low voltage, excessive current flows through the motor, which heats up, and get damaged __ Contact IQ Technologies

High Current Driver for the AD2S1200 Resolver-to-Digital Reference Signal Output -  Getting Starting The software installation procedure for the EVAL-AD2S1210 board and the EVAL-CED1Z board is described in the EVAL-AD2S1210EDZ Evaluation Board User Guide__ Analog Devices from the Lab

High Current LM317 Regulated Power Supply-  The high current regulator below uses an additional winding or a separate transformer to supply power for the LM317 regulator so that the pass transistors can operate closer to saturation and improve efficiency.  For good efficiency the voltage at the collectors of the two parallel 2N3055 pass transistors should be close to the output voltage. __

High Current Power Supply-  Since my page was first posted, I have received a number of emails asking about a high current power supply.  I looked around, but couldn't find one that was suitable.  So, I designed this.  It is a linear supply, which might have a few of you rolling your eyes, but it takes very few parts, is simple to build and can supply huge currents __ Designed by Aaron Cake

High Speed Photography-AIR Flash Unit-  Capture short lived moments using a standard camera.__

High Voltage 100mA Current Source-  An external zener diodes protects the LT3092 and allows the part to be used in high voltage applications. __ Linear Technology/Analog Devices App Note, Mar 24th 2010

High Voltage Breakdown Tester-  (Not for beginners!) The following circuit is used to determine the breakdown voltage of electronic components without causing permanent damage.  The circuit quickly ramps the high voltage up from zero and stops when the leakage current reaches a preset amount up to 100 uA.  When power is applied the two-transistor flasher circuit drives the complimentary-symmetry output stage with a square pulse at about 3 or 4 kHz(set by the 0.02 uF capacitor).  The output stage is connected to the speaker winding of an audio transformer from an old tube radio and the transformer steps the voltage up to about 250 VRMS . __ Contact:  Charles Wenzel of Wenzel Associates, Inc.

High voltage electrolytic capacitor reformer-  The mains supply voltage (220-240V AC) is half wave rectified by D1 and smoothed by C1.  R1 is a surge-limiting component, intended to limit the initial inrush current to C1.  R1 must be a wirewound component.  R2 will gradually discharge C1 and any capacitors that are connected to the output of the unit when the mains supply is switched off.  This will take about 15 seconds with C1 alone, and much longer with additional capacitors connected. __ Designed by Paul Stenning

High Voltage Electronic Dazer-  The Electronic Dazer is a modern, portable, personal-protection appliance.  It generates hight potential energy to ward off vicious animals or other attackers.  It is an aid to help exape from a potentially dangerous situation.  the device develops about 2, 000 volts.  Higher voltages mabe be attained by adding aditional multiplier stages, but it should be noted that those stage will also increase the overall size of the unit. 
The Dazer is very compact, being built into a small plastic case.  It is powered by a single 9-volt battery, either NiCad or alkaline. (Editor's Note: the so-called 9-V NiCad actually provides only about 7.5V.  Why? NiCad cells only give 1.25 per cell.6 cells in a 9volt battery gives it 7.5V and so the Alkaline type would be a better choice). __ Designed by Rick Duker

High Voltage Generator-  The simple circuit can be used at very low frequencies, RF frequencies, low voltages, or even very high voltages with careful selection of transistors.  The power handling capability and power consumption are also easily modified to suit the requirement __ Contact:  Charles Wenzel of Wenzel Associates, Inc.

High voltage generator (Domenico Di Mario)-  Easy to build, this high voltage generator is capable of generating up to 50KV but the breakdown voltage of the coil limits the voltage to a value somewhat lower.  T2 is the ignition coil of a car and also the 0.5µF capacitor comes from the same place: actually I suggest using only this type of capacitor__

High Voltage Generator for Geiger Tubes-  The following two circuits are an improvement over the older circuits below.  The circuits are shown generating 500 volts but they may be modified to supply a couple of hundred to nearly 1000 volts by changing the zener diodes.  The difference is subtle; the feedback signal increases the voltage on the base of the 2N4403 to stop the oscillator instead of stealing current from the capacitor on the emitter.  The result is much lower power dissipation when there is little or no load on the high voltage __ Contact:  Charles Wenzel of Wenzel Associates, Inc.

High Voltage Generator for Low Current Applications-  Scroll to this one -- Here is a simple circuit for generating over 100 volts from a 12 volt source for powering low current devices and experiments.  The two transistors may be 2N4401 and 2N4403 or similar for lower power applications or higher power devices for heavier loads.  If more power is desired then lower the two 10 ohm emitter resistors to 3.3  ohms.  When driving power transistors, more drive may be achieved by adding two more gates and resistors in parallel with the two output gates shown.  Notice that the two driver gates are simply in parallel with 220 ohm current limit resistors in series with their outputs. __ Contact:  Charles Wenzel of Wenzel Associates, Inc.

High Voltage Generator Project-  WARNING: This project is only for adults with a sound knowledge of electricity and electronics.  Working with high voltages and currents carelessly can cause personal injury and damage to property.  If you build this project it is at your own risk and responsibility ! ! ! __ Designed by braincambre500 @ yahoo.com

High Voltage High Current Power Supply-  A while ago I came up with the idea of using a microwave transformer as a high voltage, high current power supply.  Even though I had no use for such a supply, I decided to design one anyway.  This is a very simple design.  Note: I have not built this supply becasue I have no use for it.  If you build this supply without knowledge in electronics or high voltage, you have basically signed your own death certificate.  This supply can be very dangerous if not treated properly __ Designed by Aaron Cake

High Voltage Low Current Supply-  A high voltage power supply is a very useful source which can be effectively used in many applications like biasing of gas-discharge tubes and radiation detectors etc.  Such a power supply could also be used for protection of property by electric charging of fences.  Here the current requirement is of the order of a few microamps__

High Voltage Power Supply using a Highly Integrated DC/DC Converter TPS61040 Slva137.Htm, 0 Kb-  TI App Note __

High Voltage Solar Inverter DC-AC Kit-  Photovoltaic (PV) installations tied to the grid are usually built with arrays of modules connected in series to string inverters.  An emerging system architecture to harvest more energy per module by supplementing the conventional string inverter uses dc-dc converters dedicated to individual modules.  These systems, known as microconverters or dc-dc power optimizers address partial shading and other aging issues by implementing maximum power point tracking (MPPT) at the individual module level so that underperforming modules do not constrain the entire string __ Designed by Texas Instruments App Notes, 9-Jul-12

High Voltage Stun Gun-  This device produces high voltage pulses discrupting muscles and nervous sYstem, leaving anyone who touches it in a state of menthal confusion.  Can be used agains ferocious animals or attackers, BUT REMEMBER, this device may be illegal in your state (for eg where I live, these devices are banned).  It is quite dangeros for peoples experiencing cardiac problems, and for electronic equipment (like peacemakers) , since it generates some RF.  Don't attept irresponsible actions with this device, it is not a toy. __ Designed by Jonathan Filippi

High Voltage/Current & Temperature Monitoring-  The LTC2990 is used to monitor system temperatures, voltages and currents. Through the I2C serial interface, the device can be configured to measure many combinations of internal temperature, remote temperature, remote voltage, remote current and internal VCC. The internal 10ppm/°C reference minimizes the number of supporting components and area required. Selectable address and configurable functionality give the LTC2990 flexibility to be incorporated in various systems needing temperature, voltage or current data.__ Linear Technology/Analog Devices App Note, Oct 26th 2010

High-voltage Amplifier drives piezo tubes-  7-Dec-04 EDN Design Ideas:  Piezoelectric tubular positioners that drive manipulators in scanning tunneling microscopes require high-voltage, low-current drive circuits.  The circuit in Figure 1 can drive high-resistance, low-capacitance piezoelectric loads at a -3-dB bandwidth of 6 kHz.  It offers a low-cost alternative to commercial driversPDF has several circuits, please scroll to find this one __ Circuit Design by Bipin Duggal, Netaji Subhas Institute of Technology, New Delhi, India

High-voltage Amplifier uses simplified-  14-Oct-04  EDN Design Ideas:  Many scientific instruments and sensors need ac high-voltage drive.  High-voltage drive is useful for driving electrodes in many applications. __ Circuit Design by Jui-I Tsai, Jun-Ming Shieh, Tai-Shan Liao, and Ching-Cheng Teng, National Chiao Tung University, Taiwan

High-Voltage Capacitors, build your own!-  As one who supplies parts to those who experiment with high voltage, I get a lot of letters and phone calls from frustrated builders that go like: "Can you supply an inexpensive xxx microfarad capacitor at a working voltage of YYY? My only source wants $249 for one.  "Sometimes, a high price is justified; other times, a seller has the only capacitors of a special value available, and will soak you for the maximum dollar __ Designed by Tony van Roon  VA3AVR

High-voltage CMOS Amplifier enables high-Impedance sensing with a single IC-  06/30/14  EDN Design Ideas:  Accurately measuring voltages requires minimizing the impact of the instrument connection to the tested circuit.  Typical digital voltmeters (DVMs) use 10MΩ resistor networks to keep loading effects to an inconspicuous level, but even this can introduce significant error, particularly in higher voltage circuits that involve high resistances. __ Circuit Design by LTC Design Note

High-Voltage DC Generator-  Voltage, by definition, is the electrical pressure that causes current to flow through a conductor.  When that pressure is sufficiently high, a high voltage is produced.  But how do we define high-voltage? Is 100, 1000, or 10, 000 volts considered high voltage? When compared to 10 volts, they all can be considered high voltage __ Designed by Tony van Roon  VA3AVR

High-voltage regulator is 100%-surface-mountable-  11/24/99  EDN Design Ideas:  It can be difficult to generatea high-voltage supply from a medium-voltage input, especially if you need a surface-mount design.  It is difficult to find surface-mount components with the necessary specs, especially the transformer and power switches.  High-voltage surface-mount capacitors __ Circuit Design by Tom Gross, Linear Technology Corp, Milpitas, CA

High-Voltage, High-Frequency Amplifier Drives Piezoelectric PVDF Transducer-  24-Jul-08 EDN Design Ideas:  Finding wide use in nondestructive testing, a high-voltage, high-frequency amplifier drives a piezoelectric PVDF transducer __ Circuit Design by Enrique Vargas, Sergio Toral, Vicente González, and Raúl Gregor, Universidad Católica Nuestra Señora de la Asunción, Itapúa Antequera, Paraguay

How to Configure a Low-Power Timer/Oscillator to Operate From Higher Supply Voltages-  06/27/12  EDN Design Ideas:  Low power, low voltage CMOS timers/oscillators like the Touchstone TS3001/TS3002 are specified to operate at 1V, consuming supply currents as low as 1µA.  While the TS3001/TS3002 has an operating VDD voltage range of 0.9V-1.8V, systems running from higher supply voltages can also take advantage of the low supply currents of this micropower timer, by adding a few inexpensive transistors to the operating circuit. __ Circuit Design by Martin Tomasz

How Van De GrAAff Generators work-  Most of us have seen the device, known as a Van de Graaff generator that makes your hair stand on end.  The device looks like a big aluminum ball mounted on a pedestal.  Have you ever wondered what this device is, how it works, why it was invented, or how you might build1-yourself?__
