12 V DC: 120 VAC Inverter Schematic:  An Inverter is a device that converts 12 volts DC to 120 volts AC. , which is what we use in our homes.  This project will handle about 300 watts, which is perfect for lights, small TV's and radio equipment.  This Inverter takes 12 volt DC  and steps it up to 120 volt AC.   wattage depends on which transistors you use for Q1 and Q2, as well as  "Amp Rating" of  transformer you use for T1. This inverter can be constructed to supply anywhere from 1 to 1000 (1 KW) watts. If Q1, Q2 are 2N3055 NPN Transistors and T1 is a 15 A transformer, n  inverter will supply about 300 watts. Larger transformers and more powerful transistors can be substituted for T1, Q1 and Q2 for more power. Note: Don't try to run inductive loads (motors...) off this inverter. (added 4/05)

12 Volt DC to 120 Volt AC Inverter:  this inverter should solve that problem. It takes12 VDC and steps it up to120 VAC. -Wattage depends on which transistors you use for Q1 and Q2, as well as how "big" a transformer you use for T1.  inverter can be constructed to supply anywhere from1 to1000 (1 KW)-Watts.

300ma DC-to-AC Converter:  This circuit was used to provide battery backup to a device that had an AC (output) wall transformer. Due to  quasi-sine-wave output and imprecise 60Hz output frequency, some devices might not work properly. Peak output is  DC input voltage minus about 20 ohms drop. Use bigger output MOSFETS for more current output.  Designed by Andrew R. Morris  (added 09/05)

Bidirectionall Power Inverter:  (circuit added 1/07)

Bidirectionall Power Inverter:  08/02/01 Design Ideas EDN  If you want to swap charge in eir direction between unevenly loaded positive and negative battery buses, you need an inverting dc transformer. One implementation is  symmetrical flyback converter shown in Figure 1 . The circuit can generate a negative output from a positive supply or a positive output from a negative supply. When  circuit starts up,  substrate diode of  output FET bootstraps  output voltage to  point where synchronous switching takes over. When  gate-switching signal is symmetrical,  output voltage is approximately -95% of  input voltage, and  efficiency is greater than 80%. You can obtain voltage step-up or step-down by adjusting  switching ratio. (added 4/05)
