Description
In compact pulsed power applications, high voltage is often sourced by a DC to DC resonant converter that draws power from a manageable, lower voltage source. As the converter’s switching frequency is increased, the size of the magnetics decreases increasing overall power density. Despite its many advantages, increasing the frequency can increase the switching losses within the rectifying diodes and solid-state switches. The research presented is focused on the studying the reverse recovery losses associated with Silicon Carbide Schottky diodes used in a high voltage full-bridge rectifier at switching frequencies ranging from 10 kHz to 65 kHz. The testbed assembled to study the diodes will be presented along with the results collected to date.
