Abstract

Flyback converters are used in DC-DC conversion with electric isolation between the input and the output. In flyback converter circuits, a silicon carbide (SiC) metal-oxide-semiconductor field-effect transistor (MOSFET) and a silicon carbide junction gate field-effect transistor (JFET) are adopted as the switching and rectifying devices, respectively. SiC devices were controlled due to one signal, and a switching frequency of 1MHz was achieved. The voltage and current on the input and output sides in the flyback converter were observed as part of the circuit operation analysis. The power conversion efficiency was evaluated through waveform observation.
