Abstract
To make grid-connected power generation systems more compatible with photovoltaic
fuel cell
wind power and other clean energy power generation equipment
a coupled inductance DC-DC converter based on a new type of double-switched structure capacitor is proposed in this paper. The high gain
low loss and low switching voltage stress of the converter are realized by a novel double switched capacitor structure and a coupled inductance boost unit. Importantly
the voltage stress of the two power switches can be evenly distributed through the passive clamping circuit in the novel double-switched capacitor structure
thus reducing their peak voltages. At the same time
the leakage energy can be recovered and the efficiency of the converter can be improved. This paper introduces its operating mode and steady state analysis. The stresses and theoretical efficiency of the components are analyzed and compared with other DC-DC converters. Finally
according to the design criteria
a 200 W prototype was built in the laboratory to verify the effectiveness of the proposed converter.
