摘要：

Demand for high-power dc fast chargers for electric vehicles (EVs) is growing. In this paper, an outline and control of a SiC-based 60-kW high-efficiency level-3 dc fast charger is narrated. The three-phase EV ac/dc battery charger is based on the patented differential-mode converter topology. Such differential-mode rectifiers (DMRs) are single-stage ac/dc converters that reduce the number of controlled switching devices and hence, the system cost while achieving higher power density and higher efficiency. A control formulation demonstrating power-factor-correction (PFC) based unity-power-factor (UPF) operation with low total harmonic distortion (THD) is presented. Simulation results containing steady-state operation, transient waveforms with loss analysis, efficiency, and THD parametric plots are presented.
