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.

“…In [39], an on‐board V2G charger with a bidirectional energy flow capacity is adopted, ensuring a transfer of the bidirectional AP and guaranteeing an improved power factor. In [40], the authors have proposed a V2G charger with a very reduced capacity to guarantee the charging and discharging of the EV battery and by generating an improved power factor. In [41, 42], the RP capability of the V2G charger has been adopted to strengthen the grid.…”

“…Research on the effects nolinear loads on APLCs has been scarce. The instantaneous active-reactive power theory in three-phase circuits, originally proposed by H. Akagi The authors of another study proposed a novel reactive power control strategy with CDCVC blocks for the APLCs in both TPFWLVDFs and single-phase three-wire low-voltage distribution feeders (SPTWLVDFs) (10) (11) . The simulation and experimental results proved that the balanced and sinusoidal source currents were achieved only when the CDCVC block controlled the reactive power.…”

This study demonstrates that a proportional-integral (PI) controller in the constant DC-capacitor voltage control (CDCVC) block of a four-leg active power-line conditioner (APLC) in three-phase four-wire distribution feeders (TPFWDFs) accurately calculates the root-mean-square (RMS) value of the fundamental active currents in the feeder currents, using simulation and experimental results. The accuracy of the RMS value calculated by the PI controller in the CDCVC block is crucial because the reference signals for the source currents are calculated using the RMS value calculated in a previously proposed CDCVC-based strategy for the four-leg APLC in TPFWDFs. In this study, the previously proposed CDCVC-based strategy is modified by adding an algorithm for calculating the fundamental active currents in the feeder currents. The basic principle of the modified CDCVC-based strategy is discussed in detail and confirmed by digital computer simulations using a power electronics simulator (PSIM). A scaled-down experimental set-up is developed and examined. The simulation and experimental results demonstrate that the PI controller in the CDCVC block of the four-leg APLC accurately calculates the RMS value of the fundamental active currents in the load currents. Therefore, it is concluded that the previously proposed CDCVC-based strategy for a four-leg APLC is applicable to the four-leg APLCs in practical TPFWDFs.
