WebI. INTRODUCTION M ANY power switching circuits require a freewheeling diode in parallel to the switch. While in a power MOSFET the integral body diode is used as a freewheeling element [1], in the IGBT, an external diode is needed to conduct the reverse current. This results in increased space and cost.
