Abstract

This paper presents the design and the implementation of a 20 kW power module (PM) for electric vehicle fast chargers. The proposed PM includes an AC/DC converter using a T-type neutral-point-clamped (TNPC) topology and an isolated DC/DC converter that uses an LLC resonance topology to minimize the switching losses. A cooperative control strategy is proposed to achieve a parallel operation sequence of PMs while considering the actual EV charging sequence. Experimental results validate the effectiveness and the reliability of the proposed PM for various load conditions, and the feasibility of the cooperative control strategy is confirmed through the parallel operation with four PMs. Experimental results show a highefficiency power conversion of up to 97%.
