This paper presents a loss-optimized Triple Phase-Shift (TPS) switching strategy for Dual-Active Bridge (DAB) based converters. The proposed strategy considers minimizing total converter loss with respect to minimizing device rms cur-rents, enabling Zero-Voltage Switching (ZVS) turn-on of devices and accurate control of device turn-off current. A model for switching currents is presented, followed by a loss model and optimization strategy. A 1.3kV/100kW prototype based on SiC MOSFETs was used in this work and experimental results up to 10kW show the proposed TPS strategy to be more efficient for operation.
