High Boost DC-DC Converter Based on Switched Inductor, Switched Capacitor and Voltage Multiplier Cell

An integrated switched-capacitor (SC), voltage multiplier (VM) cell and switched-inductor (SL) based high gain DC-DC converter is put forward here. This suggested converter boosts the low voltage obtained from fuel cell or solar photo voltaic (PV) to make it suitable for grid integration. This converter is highly efficient with a gain of 89 when operated with 0.8 duty ratio. The suggested converter switches and diodes are under low voltage stress. In order to validate simulation results, a 100 W, 200 V prototype model is set up in the laboratory for 24 V input. According to the experimental findings, the intended converter is highly effective, owing to its high gain, low switching stress and low duty cycle.
