ABSTRACT:
An inverter circuit includes a first driving transformer, a second driving transformer, a power voltage circuit, a high-side FET connected to a secondary winding of the first driving transformer, a low-side FET connected to a secondary winding of the second driving transformer and an inverter transformer connected to a driving node between the high-side FET and the low-side FET. Thus, a direct current path does not exist between a gate of the high-side FET and the driving node, so that a gate voltage of the high-side FET is biased more to a negative polarity.
