摘要

Today, wide bandgap devices with either gallium nitride (GaN) or silicon carbide (SiC) are commercially available from multiple vendors and the number of devices and vendors is increasing. The use of these wide bandgap devices for power converters compared to more widely used silicon devices offers multiple benefits for military power converters. The benefits include higher temperature operation and improved device characteristics which result in lower device and converter losses and improved power density. The converters described in this paper are a first step in realizing these benefits using existing SiC devices packaged into larger power modules.
