Wide Bandgap Bi-Directional Converter

This Phase II project is to design, build and test a bi-directional converter (BDC) utilizing wide-bandgap devices. The proposed BDC will be capable of converting 15kW power continuously between 600Vdc and 28Vdc voltage buses and fit into a ARINC 600 6-MCU enclosure. Utilizing wide bandgap technology devices including SiC and GaN MOSFETs enable the BDC to operate in a 71 Celsius ambient environment. During Phase I period, Galley Power has built and tested proof-of-concept prototype for the proposed BDC and demonstrated its feasibilities with key functionalities meeting or exceeding the performance requirements. In Phase II period, a full-scale BDC will be designed and built based on the Phase I prototype. Lab tests will be conducted on the BDC to prove its functions. The BDC will be designed with appropriate electrical and mechanical interface for integration into a military ground vehicle system.
