Closed Loop Control of Isolated Bidirectional DC to DC Converter with High Conversion Ratio

A bidirectional dc to dc converter is necessary between the energy storage battery and the supply to match the voltage level. For high to low power range application bidirectional isolated converter is proposed. The isolated bidirectional converter is operated in both step down and step up modes. In this work, Bidirectional Isolated DC-DC converter is designed to operate with high conversion ratio and high efficiency. By using a voltage doubler circuit in high voltage side increase the conversion ratio .The simulation of the circuit with high voltage of 200V, Low voltage of 24V input, and output power of 200W is done using MATLAB. Closed loop control scheme is used to generate the gate pulses.
