Inductor dc bias
Web18 dec. 2024 · Abstract: In this brief, a 400-W Gallium Nitride device based DC-DC boost converter with a four phase matrix inductor is proposed. It is well-known that there is a significant influence of the DC bias on inductor core losses and the simplest solution is to employ multiphase structures.
