Circuits Designed by Dave Johnson, P.E. :

LOW POWER 12,000 VOLT POWER SUPPLY
If you need about 12,000 volts DC for an ion generator this circuit might be the ticket. It draws power from the 120vac power line but it uses a small 6KV camera flash trigger coil. The output signal is isolated from the power line. Although the circuit can only deliver about 5uA of current it can produce dangerous shocks, so be careful.

SIMPLE NITROGEN SPARK GENERATOR
Nitrogen or air sparks are very powerful light sources that produce flashes that last only a few nanoseconds. This line powered circuit generates a continuous series of very small sparks across electrodes with a 0.05 inch gap.

High Voltage Amplifier Drives piezo tubes: 12/07/04 EDN Design Ideas / (added 6/05) 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 drivers.

High Voltage Amplifier uses simplified circuit: 10/14/04 EDN Design Ideas / (added 5/05) Many scientific instruments and sensors need ac high-voltage drive. High-voltage drive is useful for driving electrodes in many applications. The challenge is to boost the output of a conventional op amp to high voltages. Available ac high-voltage amplifier modules are limited to approximately 1200V p-p.

High Voltage Regulator is 100% surface mountable: 11/24/99 EDN Design Ideas / (added 2/06) 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 can also be hard to locate. The circuit in Figure 1 generates 100V from 25V. The circuit is a typical flyback regulator that uses a couple of well-established circuit techniques to handle the high voltage. The first technique is to insert an n-channel MOSFET (Si4480) in series with IC1's internal power transistor. The cascoded FET stands off the large switch voltage that arises when the switch turns off. The large switch voltage represents the input voltage summed with the reflected output voltage of the...
