Silicon Carbide Based Power Mangement and Distribution for Space Nuclear Power Systems, Phase I

Completed Technology Project

Project Introduction

In this SBIR project, APEI, Inc. is proposing to develop a high efficiency, rad-hard, 100's kWe power management and distribution (PMAD) system for space nuclear power systems. The PMAD will utilize SiC JFET power switches; components which APEI, Inc. has irradiated under TID conditions to greater than 3MRad with little to zero change in device performance. The PMAD will implement a modular approach in order to increase efficiency and ease expansion, as well as a multi-level soft-switching power topology which will allow increased transmission voltages (up to 2 kV) and increased efficiency. APEI, Inc. will leverage over a decade of experience in developing high-power, high-density SiC-based power electronic systems in order to realize an efficient, power-dense PMAD solution for space nuclear power systems.
