Soft-Switching Full-Bridge Converter with Multiple-Input Sources for DC Distribution Applications

Due to the advantages of power supply systems using DC distribution method, such as a conversion efficiency increase about 5–10%, cost reduction 15–20%, etc., AC will be replaced by in future. This paper adopts different converters generate system: DC/DC converter with PV arrays, factor correction utility line and full-bridge multiple input sources. With this approach, proposed soft-switching features for generating desired voltage level order transfer energy system. In addition, is used applied balance between arrays line. features, can operated zero-voltage switching (ZVS) at turn-on transition efficiency. Finally, prototype under an 48 V, output 24 maximum current 21 A 500 W was implemented prove its feasibility. From experimental results, it found that 92% 50% full-load conditions. It shown suitable applications.
