Abstract

Battery Charger Regulator (BCR) circuit used on spacecraft power systems, are usually switching regulators to provide maximum power for current operation mode and fixed voltage for voltage mode. In this article, we present detailed design procedures for BCR implemented on Cube-satellite. We will show small-signal analysis of a battery charger, to perform the control loop design of the maximum power point detection step and also voltage mode control loop to detecte battery Endof- charge. We present also a simulation of tow loops to verify our design.
