Natural‐air‐cooled 5 kVA single‐phase GaN inverter with paralleled multilayer PCB magnetics
The Journal of Engineering, Volume 2018, Issue 2, Page 94-103, February 2018., 2018 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
