A High Step up Boost Converter Using Coupled Inductor with PI Control

Saurabh, Dr.P.K.Saha, Dr.G.K.Panda

The paper proposes a high step up boost converter. The proposed converter has used a coupled inductor with switched capacitors. The capacitors were made to get charged in parallel and were made to get discharged in series by the configuration to achieve high step up voltage gain. And the voltage across the load is maintained constant by using a closed loop control. The operation and steady state analysis of the configuration has been shown in detail. Finally, a circuit with 24-V input, 400-V output, and power of 200W has been implemented in MATLAB software to verify the proper working and performance of the proposed configuration.
