This paper investigates the application of a vehicle-to-grid (V2G)-enabled bidirectional off-board electric vehicle (EV) battery charger on the grid current harmonic compensation (GCHC) and reactive power compensation (RPC) and simultaneously uses it as a battery charger and power generator. To generate reference current, the proposed EV charger control algorithm processed the nonlinear residential load current and point of common coupling (PCC) voltage, to estimate the active load current component and synchronizing voltage template, respectively. The EV charger control algorithm uses an adaptive notch filter (ANF) to generate the in-phase and 90° shifted synchronizing voltage template from PCC voltage. Furthermore, a resonant filter is used to extract the fundamental frequency residential load current component accurately. The extracted fundamental component is sampled and hold at zero crossings of the 90° shifted synchronizing voltage template to estimate the active load current component. As a result, the proposed control algorithm ensures effective performance without depending on any phase-locked loop (PLL). The charger performance with the proposed control algorithm is validated by the simulation results obtained using MATLAB/Simulink. Furthermore, an off-board EV battery charger experimental prototype is built in the laboratory to verify the obtained simulation results.
