- Abstract
- In this paper, tapped-inductor based high efficiency and high-power density Zero-Voltage and Zero-Current Switching (ZVZCS) boost converters are proposed for 8 kW PV applications. The proposed converter uses only one SiC switch and three SiC diodes for turn-on ZCS and turn-off ZVS operations, resulting in an efficiency of over 98.2%, higher than that of the conventional converter (97.3%) which uses two switches and two diodes, considering switching and conduction losses. The proposed converters are applied to 500 V and 800 V of input and output voltages for PV, respectively, and verified by simulation analysis and experimental setup with SiC high frequency switching devices manufactured from PowerCubeSemi Co., Ltd.
