audioguru Posted September 27, 2013 Report Share Posted September 27, 2013 It is easy to take a 12VDC power supply or battery, make an oscillator feeding Mosfets and have a square-wave output at 12VAC. Quote Link to comment Share on other sites More sharing options...
Guest Kaash Posted September 28, 2013 Report Share Posted September 28, 2013 will you sketch simple circuit diagram thanks. Quote Link to comment Share on other sites More sharing options...
audioguru Posted September 29, 2013 Report Share Posted September 29, 2013 A 555 oscillator driving complementary power transistors as emitter-followers that drive a power transformer connected in reverse. The maximum output power will be about 50W.The waveform will be a crude square-wave. The voltage will be too high when the load is low power and the voltage will be too low when the load is high power. It will smoke and burn if it is overloaded.It will not shut off when the battery gets low so the battery might be destroyed.But it is simple and cheap!
