Abstract :
A model to evaluate power MOSFET switching loss is developed. Frequency dependencies are measured using a one-transistor forward converter and compared with calculated ones. For comparison, maximum output powers are measured both for power MOSFETs and bipolar transistors. To reduce the switching loss and enable a faster switching a small feedback capacitance device is proposed and realized.
