Abstract
In a three-phase inverter configured driving circuit and method, three switch assemblies are connected in parallel between an input voltage and a reference voltage and switched to generate a three-phase AC voltage on the primary side of a three-phase transformer, so as to be transformed to a three-phase current from the secondary side of the transformer to provide for three loadings.
