This inverter circuit can convert 12 volt DC voltage into AC voltage of 220 volts with a Modified Sine waveform or better known as the “Modified Sine Wave Inverter”. This inverter circuit has a modified sine wave output, so it has a better power efficiency than an inverter with square wave inverter type. Inverter circuit “Modified Sine Wave” is simple enough to be made, this inverter circuit built using the IC LM555 astable multivibrator, jonhson STP36No6L counter CD4017 and MOSFET as a power inverter. And a complete range of components to make a list Modified Sine Wave inverter can be seen in the following figure. DC 12V to AC 220V Modified Sine Wave Inverter Circuit Diagram Above the inverter circuit comprises a square wave generator (IC LM555) with a working frequency of 200Hz is used as a clock input johnson counter IC CD4017 as a modifier to be used as a square wave signal so that the output MOSFET drivers STP36N06L transformers form a modified sine wave.
