要約(英語): This paper addresses power quality compensation with a constant DC-capacitor voltage-control (CDCVC)-based reactive power control method for a three-leg pulse-width modulated (PWM) rectifier in a bidirectional battery charger (BBC) for electric vehicles (EVs) in commercial single-phase three-wire low-voltage feeders, considering two domestic consumers. The instantaneous power flowing into the three-leg PWM rectifier demonstrates that the balanced and sinusoidal source currents, with a predetermined power factor (PF), are obtained in the domestic consumer equipped with the BBC, whereas the unbalanced and distorted source currents remain in the domestic consumers without the BBC. The simulation and experimental results show that the balanced and sinusoidal source currents at a PF of 0.90, which is a predetermined value, are obtained in the domestic consumer with the BBC, whereas the unbalanced and distorted source-side currents remain in those without the BBC. These simulation and experimental results demonstrate that controlling the reactive power on the source side with the CDCVC-based strategy reduces the capacity of the three-leg PWM rectifier in the BBC for EVs.
