HIGH FREQUENCY DC/DC CONVERTER BASED ON SIC TRANSISTORS FOR RES APPLICATION


Abstract

The paper presents the concept of the design, construction and test results of the voltage DC/DC Buck-Boost Converter up to 1 kW with silicon carbide transistors (SiC JFET). The inverter is designed to work with the supercapacitor energy storage bank as voltage stabilization system in multi-source renewable energy sources (RES) laboratory stand. Small conduction losses and low switching energy of SiC JFET transistors make possible to increase the operating frequency of the inverter to 500kHz. Conducted laboratory tests confirmed the high efficiency model of the inverter at 95%.
