摘要: High-voltage-gain step-up DC-DC converters are required for the applications of distributed energy resources (DERs). A family bidirectional switched-capacitor (SC) with high gain ratio any positive integer proposed in this paper. These efficiency, easy to control, and low output voltage ripple less than 1%. The also capable delivering power, which is a key requirement battery storage. prototype 9-time SC converter at 20 V input voltage, 100 W output, 75 kHz, built tested. Experiment results show that maximum efficiency over 98% without driver's loss entire load range between 25 95.5% including loss.
