| Abstract |
This paper presents an isolated three-phase bidirectional AC-DC converter with a novel modulation strategythat enables Zero-Voltage-Switching (ZVS) for all switches over the whole AC line period. The AC-DCconverter allows the direct coupling of a three-phase AC system with a DC port applying a singlehigh-frequency transformer. A novel modelling approach for the power flows and the derivation of thecontrol variables under ZVS conditions are provided. The design of components including loss modelsand simulation results of a 11 kW electric vehicle battery charger to connect to the 230 Vrms, 50 Hz mainsconsidering a battery voltage range of 380 V to 540 V validate the theoretical analysis. |
