Abstract
This paper aims at the overview in design and development of reliable and robust space grade power supplies for satellite subsystems. The satellite is using six types of power supplies modules (PSM) which provide total of 20 isolated outputs. All converters are designed by using forward converter topology followed by post-Mag-Amp regulator for each output to meet the required specifications. Voltage mode with feed-forward control technique has been adopted to provide better CS101 performance. The converters deliver the output power from 15 to 110 W for different PSMs for the lower input voltage range of 32–42 V at a switching frequency of 150 kHz with sync. This paper also covers specification, design procedure and practical test results. Flight models have been developed, and practical electrical results have been validated in environmental tests like thermo-vacuum cycling test, operational temperature test, vibration test, etc.
