Present high power density Si-based systems are severely limited by the electrical and thermal performance of active and passive components as well as electronics packaging technology. As a result, the next-generation of radar power supply systems require a new and revolutionary power electronics technology that delivers far superior efficiency, response time, thermal performance, and miniaturization capability. This Small Business Innovation Research project seeks to develop high-voltage (up to 1000 VDC), highly efficient (>90%), and compact (>200 W/in3) next-generation radar power supplies utilizing emerging Wide Band-Gap (WBG) power devices in conjunction with advanced non-linear control and high power density packaging techniques. The new WBG-based radar power supply technology will be capable of fast response time (rise and settling times
