Wide Band Gap (WBG) semiconductor technologies such as Silicon Carbide (SiC) and Gallium Nitride (GaN) are being replaced with Silicon (Si) MOSFETs and IGBTs in power switching converters. In hard-switching applications, GaN is more attractive because of its lower switching power losses. The DC-DC power module of the motor drive in Plug-In Electric Vehicles (PEVs) has a power rating range of 30-150 kW while the power rating of GaN is not that much high. A two-phase SiC-GaN-based converter can satisfy the demanded power, achieving the advantage of WBG technology, and avoid the complexity of multi-phase converter with high number of phases. Obtaining the maximum efficiency, the power sharing is not symmetrical. Therefore, a cascade controller is considered in this paper to control fully directional universal converter: drive/plug-in, boost/buck mode. The simulation results prove the satisfactory performance of the controller in all modes of operation.
