This paper discusses the harmonics compensation of the constant dc-capacitor voltage-control (CDCVC)-based strategy of smart charger (SC) for electric vehicles (EVs) in single-phase three-wire distribution feeders (SPTWDFs) under the distorted source voltage and load currents conditions. The basic principle of the CDCVC-based harmonics compensation strategy under the distorted source voltage and load...
This paper discusses reduction of capacitances of dc capacitors in the previously proposed smart charger (SC) with a sinusoidal charging-discharging lithium-ion battery for electric vehicles in single-phase three-wire distribution feeders. The dc-capacitor current of the three-leg pulse-width modulated (PWM) rectifier, which is included in the SC, is detected, and then added to the reference value...
This paper addresses compensation performance of the constant dc-capacitor voltage-control (CDCVC)-based strategy for smart charger with the previously proposed reactive power control algorithm in single-phase three-wire distribution feeders (SPTWDFs) under distorted source voltage conditions. The instantaneous power flows into the smart charger is discussed in detail. This instantaneous power flowing...
This paper presents an improvement in the harmonics compensation performance of a previously proposed smart charger (SC) with a constant dc-capacitor voltage-control (CDCVC)-based strategy for electric vehicles (EVs) in single-phase three-wire distribution feeders (SPTWDFs). A current controller of a three-leg pulse-width modulated rectifier with proportional-integral (PI) controllers in d-q coordinates...
This paper proposes a novel and simple harmonics compensation strategy that can control the fundamental reactive current in the previously proposed smart charger (SC) for electric vehicles (EVs) in single-phase three-wire distribution feeders (SPTWDFs). The proposed harmonics compensation strategy uses only constant dc-capacitor voltage control (CDCVC), which is typically used in grid-connected pulse-width...
This paper proposes a novel reactive power control strategy to reduce the capacity of the previously proposed smart charger for electric vehicles (EVs) on single-phase three-wire distribution feeders. The proposed reactive power control strategy is based on the constant dc-capacitor voltage control of the grid-connected pulsewidth-modulated rectifier. Any calculation blocks of the load-side active...
This paper address compensation performance for the previously proposed smart charger of Electric Vehicles (EVs) with constant dc-capacitor voltage control under multiple household customers. No calculation blocks of the reactive and unbalanced active components on the load side are used in the previously proposed control strategy. The smart charger with the constant dc-capacitor voltage control based...
This paper proposes a novel and simple control method for the previously proposed smart charger for electric vehicles (EVs) on single-phase three-wire distribution feeders. The proposed method consists of only the constant dc-capacitor control, which is commonly used in active power line conditioners. No detection blocks of harmonic, reactive, and unbalanced-active currents are required. Thus, we...
