Abstract

A power electronics module is arranged to pass power between a traction battery and electric machine, and includes a pair of parallel power transistors and a differential mode choke arranged to, responsive to current flow through the choke, drive gate voltages of the power transistors apart to reduce differences in current magnitudes output by the transistors.
