Non‐isolated resonant link DC–DC converter for use with GaN devices

Abstract

As new wide band‐gap (WBG) devices are developed and improved, new topologies and control schemes are required to take advantage of the ultra‐fast switching turn on/off speeds that are now available, without the limitations of switching losses and unacceptable EMI from fast switching transitions. This paper presents a non‐isolated DC–DC resonant link converter that allows for soft switching over an extended load range that is particularly suited to GaN devices.
