Abstract

Multi-output DC-DC converters are widely used in many applications such as military, communication automobile, space application etc.. The DC-DC converters which is used for aerospace applications, has important role in ensuring the complete success of the mission. DC-DC converter is used for providing a regulated voltage to various subsystems of satellites with variation in input voltage and output resistive load. Different types of DC-DC converters were analyzed and out of all DC-DC converters, push-pull converter achieves tight regulation in the output voltage, So a push-pull converter for low power is designed for providing regulated power supply to the spacecraft. This paper deals with the design and closed loop implementation details of cascoded multi output push-pull converter with PWM controller IC (UC 3825). The results obtained in simulation and hardware implementation is presented and analyzed in detail for 9W, 50 kHz laboratory prototype developed.
