Abstract
A bi-directional Class D half-bridge power amplifier circuit incorporates soft switching components to reduce switching losses by commutating the voltage across the high and low switches of the half-bridge. The power amplifier may further be embodied in an AC power inverter configured to generate 60 Hz sinusoidal current from a DC power source. The AC power inverter may further incorporate an active filter circuit including a current shunt resistor and negative feedback loop to attenuate ripple current from the DC power source by supplying a compensating ripple voltage to the AC power inverter.
