## 12 volt to 220 volts:

This is a 12-volt to 220-volt inverter circuit diagram. this diagram can make 100 watts. 1 pair of MOSFET can make 100 watts. if we want to make more watts we have to use extra mosfet. Just make parallel the MOSFET and use a big transformer. here the transformer is 12-0-12 volts 10 amperes and 220 volts 1/2 amperes transformer. if you want 200 watts then you have to use 12-0-12 volt 20 amperes and 220 volts 1 amperes transformer and 4 mosfet.

Here needs a 12-voltage battery. minimum 8 amperes.

## Audio amplifier circuit:

This is an easy audio amplifier circuit diagram. this circuit runs with 12 voltage to 30 voltage. but here the output transformer is for 12 volts so we have to use 12 volts. if we want to use 24 voltage we have to use a 24 voltage output transformer. the output audio is 0-4-8 ohms.
