Abstract:
A bridge leg switching a DC voltage to produce an AC voltage at its output terminal for supply to an inductive load. The bridge leg has first, second, third, and fourth switch assemblies, and at least a first inductive element. The first and second switch assemblies are serially connected between the bridge leg input terminals, the bridge leg output being formed at a point of interconnection of the first and second switch assemblies. The third and fourth switch assemblies are serially connected between the bridge leg input terminals, the inductive element being connected between a point of interconnection of the third and fourth switch assemblies and the bridge leg output. The third and fourth switch assemblies are controlled such that reverse current through either of the first or second switch assembly is reduced compared to bridge leg output current prior to the moment the bridge leg output is switched.
