This paper proposes a parallel control method of a modular DC/DC converter for electric vehicle (EV) chargers. The EV chargers have been increasing

the power capacity using modular converters. There are output current imbalances between the modules, which are caused by the difference of the

impedance, delay of the gate driver, and error of the sensors. The conventional strategies for the equal distribution of the output current cause the

voltage drop or the high volume and cost of the converters. Therefore, the proposed parallel control strategy effectively balances the output current of modules using a current compensation method. The proposed strategy is verified by simulations. Additional experimental results will be added under

various conditions.
