A Novel High Gain DC-to-DC Boost Type Converter Employing Switched-Inductor

Abstract

The paper introduces a novel high voltage gain DC-to-DC boost type converter. The proposed topology is based on the switched-inductor structure. Compared to a classical boost converter for the same input and output voltage gain, the proposed topology reduces voltage stress across semiconductors and capacitor. Besides that, a high voltage gain can be achieved with a small duty cycle. Circuit analysis, operating theories, and a guideline of passive components selection of the proposed high voltage gain DC-to-DC boost type converter are presented. Simulation results in PSIM software with 25 V input voltage, 400 V output voltage at output power of 800 W are shown to verify the theoretical analysis
