Abstract:
A design methodology that leverages the performance and reliability of SiC cascodes in TO-247 packages to cost effectively implement high performance, high power converters is described and demonstrated. By paralleling complete converter legs, which include gate drive circuit, DC bus capacitance, and cascodes in TO-247 packages, a converter design that features high speed switching with minimal ringing and well balanced power dissipation can be easily achieved. The design principle is introduced and test results from a hard switched half bridge converter are presented.
