Abstract

Currently, there is a growing prominence on using switched capacitor and switched inductor techniques in high-power boost converters to achieve higher voltages. This is accomplished by employing reactive elements, where the inductor discharges while the capacitor charges. The switched capacitor and switched inductor can extremely attain dc voltage obtain with require few quantities like inductors, capacitors, diodes, and a switch. Modifications were made to the switched inductor converter, resulting in a reduction in the voltage stress on the active switch. The converter now operates based only on the duty ratio. This study suggests adjustments to the switched capacitor and switched inductor converter to decrease the stress on the switch by altering the duty ratio closer to unity. The paper covers the converter's operation, waveforms, design equations, and simulation results to illustrate this modified converter setup.
