Natural-air-cooled 5-kVA single-phase GaN inverter with paralleled multilayer PCB magnetics

In this study, a systematic approach to the design and development of a high-efficiency, natural-air-cooled, single-phase inverter with a multilayer high-current printed-circuit board (PCB) magnetics is presented. The size and efficiency of inverters implemented with the silicon transistor technology have almost reached a certain limit. The use of wide bandgap power semiconductors, such as the sil...
