Note that this is not a viable circuit since an AmpOp has very limited current driving.
This is a demonstration of an Inverter circuit. It has a sine wave generator to be modulated in a high frequency sawtooth or triangular wave. The modulation is done by a comparator circuit. It then outputs a PWM signal that can be filtered by a lowpass LC filter. The capacitor outputs the filtered PWM signal (sine wave) that can be used to power an AC load.
Normally the PWM output drives a H bridge transistor circuit with complementary action so no shortcircuit occurs. The LC filter should be used in the H bridge load.
