Here is a simple 12 volts DC to AC inverter circuit. This 120V AC power source is built with a simple 120V:24V or 110V:24V center-tapped control transformer and four additional component. This circuit ...

To test this, just attach a low-pass filter to D3 (or D11) as indicated in the wiring diagram ... a power inverter circuit that uses Arduino to generate the PWM signals and readily available N-channel ...
