摘要
In order to reduce the charging current ripple caused by distorted grid voltages, this paper proposes a charging current ripple suppression strategy for three-phase Power Conversion System (PCS) based on DC-side harmonic current compensation. The theoretical analysis and mathematical derivation of charging current ripple are presented. Based on the analysis, the range of passive components of the auxiliary branch is calculated. The auxiliary branch adopts three-loops control, including capacitor voltage controller, inductor current controller and 6th and 12th harmonic current suppression modules. The feasibility of the proposed strategy is verified by PLECS simulation.
