An approach for controlling operation of an electrically symmetrical electric power circuit is described herein to reduce common mode leakage currents. The approach can include, for example, a controller circuit configured to control a plurality of switches of the electrically symmetrical electric power circuit, such that one or more electrically symmetrical pairs of switches of the plurality of switches are operated at a same operational state when the power circuit is coupled to an electrical grid to reduce the common mode leakage current. A variant is also described that is adapted for current ripple and overall THD distortion reduction, which can be useful for vehicle to grid power transfer situations.
