Family of Transformerless Active Switched Inductor and Switched Capacitor ?uk DC–DC Converter for High Voltage Gain Applications

摘要

This article presents a family of transformerless active switched inductor and switched capacitor ?uk high voltage gain dc–dc converters. The configuration of this family has the advantages of nonpulsating output current, high step-up voltage gain, low voltage, and current stress across the component. Thus, conduction losses are decreased owing to the low-voltage-rating of the semiconductors. The ?uk converter with two switched-capacitor cells is evaluated in detail. The experimental results are provided to verify the theoretical analysis.
