Abstract
In this paper, a single-phase multifunctional onboard battery charger with small DC-link capacitors is proposed, where the low-voltage battery charger is utilized as an active power filter to mitigate the inherent second-order ripple power when the high-voltage (HV) battery is charged from the grid. In this scheme, the large DC-link electrolytic capacitors of the HV battery charger can be eliminated without additional switches, leading to the reduction of cost and volume of the onboard battery charger. The validity of the proposed topology has been verified by the simulation results.
