The DC-DC converter of a Spacecraft is one of the vital components of a satellite, which has a major role in ensuring the complete success of the mission. For providing a regulated voltage to various subsystems of satellites with variation in input voltage, DC-DC converter comes in picture. This paper presents the design and implementation of 30W flyback converter for providing supply for the telemetry tracking transmitter subsystem of the satellite. The input EMI filters responses and compensator for PWM UC1825 is simulated in MATLAB. The requirements for space applications are taken into consideration while designing and is successfully implemented.
