위성 SAR 모듈화 구현을 위한 전원회로 설계 및 해석

KOrea Multi-Purpose SATellite (KOMPSA T) uses software-controlled unregulated bus system m which the main bus is directly connected to a battery and the duty-ratio for PWM switch is generated by the on-board satellite software algorithm. In this paper, we propose a new power-stage circuit that can be available for modularization of a solar array regulator(SAR) which is used in the KOMPSAT. The operations at each mode and current sharing characteristics of the power-stage are analyzed and verified by simulation and experiments on a prototype converter
