Question

"Class D" Inverter?

I need a 100 kHz, sinusoidal AC constant-voltage power supply, feeding an inductive load.

Can i make a power inverter designed like a class D audio amplifier.

Except, instead of a speaker, it's a hungry power load that wants up to 20A, 5V AC power.

Can any chip or set of chips make this easy, for a 100W inverter?

I assume to regulate output voltage, i would change the amplitude of the input sinewave.

Looking for lowest-parts-count solution.
