A high power general purpose SiC converter for DoD and Industrial power conversion applications.

SatCon proposes to make use of prior work on SiC and advanced packaging for power converters to design and demonstrate a SiC semiconductor based power converter on the order of 60kW able to process 450VAC, thus demonstrating the capability of meeting the needs of multiple medium power applications. SatCon has investigated packaging multiple SiC diodes on ceramic based mini-modules, (SatPak).. This general-purpose mini-module/discrete works well with conventional manufacturing flows while providing superior power handling and ease of integration. SatCon would work with the SiC component supplier to develop a mini-module with SiC components. Multiple mini-modules can be paralleled to get the requisite current handling. SatCon would also take its work on SiC device drivers and develop a gate drive that would interface with one of SatCon's standard DSP based control cards. This whole assembly will be mounted to a heat sink. Phase 1 would develop a preliminary design for the SiC converter, choosing devices and working with the vendor on the design of the mini module. Phase 1 Option would provide a detailed analysis of the conceptual converter. Phase 11 would complete the design of the high power general purpose SiC converter and build a demonstrator.
