Switched-mode power-supply (SMPS) converters find use in a wide variety of applications, ranging from a fraction of a milli watt in on-chip power management to hundreds of megawatts in power systems. In this paper, a multiple output dc-dc converter based on Two Switch Forward Topology is designed and developed. The power module consists of a converter which delivers constant voltage outputs frominput battery supply. Converter works in closed loop mode with necessary compensation circuits to meet the output regulation requirements for change in load. Loop Feedback is closed by make use of control winding. Input output isolation is met using gate drive transformers. The multiple output dc-dc converter is designed and investigated by using ICAP/4 using PWM controller UC1825. The simulation results have demonstrated that the proposed converter delivers constant voltage outputs with high reliability.
