Battery discharge regulator for space applications based on the boost converter

When a DC/DC converter is used to control the power on the main bus of a spacecraft it needs to comply with highly demanding requirements from the dynamic point of view. Hence, converters with very good dynamic performance, i.e. with no zero on the right-half plane are typically used. The conventional boost converter has not been used in European space applications mainly because of its poor dynamics. This paper addresses the way of using a boost converter in this application and demonstrates that this converter can cope with the very demanding requirements needed. A prototype has been built and tested to proof it.
