The High Technology Foundation’s Power Electronics and Electromagnetics team is developing AC/DC, DC/DC, and DC/AC power converters for microgrids and distributed energy applications. A ruggedized DC/DC converter capable of 60 kilowatt operation in moderate-sized microgrids has been built. The unit is hermetically-sealed and capable of operation in harsh environments under extreme ambient conditions. The unit is designed to allow power combining of multiple units on a single transmission line. To couple AC generators to the DC/DC converter, a 60 kilowatt 3-phase AC to DC converter has been designed in detail. The AC/DC converter is power-factor-corrected so that optimal source loading is assured. The unit is designed for two-way power flow to accommodate regenerative loads such as electric motors.
