ABSTRACT:
A full bridge inverter includes a push/pull control chip outputting a first control signal and a second control signal. Each duty cycle of the two control signals is smaller than 50%. Moreover, both a first driver and a second driver are coupled to the push/pull control chip and a DC power. A full bridge switch assembly with four N-MOSes couples to the DC power, the first driver, the second driver and a transformer, and converts the DC power into an AC power by the first driver and the second driver. The AC power is transmitted to a first side of the transformer.
