Abstract

In this paper, a novel constant switching frequency hierarchical deadbeat predictive direct power controller with dynamic power estimator (HDP-DPC-DPE) is proposed for the 3-level active-neutral-point-clamped (3L-ANPC) active-frontend (AFE) rectifier for electric vehicle (EV) charger applications. In the proposed HDP-DPC-DPE, two new deadbeat predictive controllers are proposed for the outer dc-link voltage and the inner power control loops. First, a novel deadbeat predictive controller using DPE is proposed for the outer-loop dc-link voltage control of the AFE rectifier. Second, a novel constant switching frequency deadbeat DPC is suggested for the inner-loop power control. The proposed HDP-DPC-DPE is robust to power grid distortion due to elimination of the phase locked loop (PLL). Moreover, the proposed HDP-DPC-DPE provides fast dynamic response, robustness to parameters variations, constant switching frequency, continuous sinusoidal input current and unity PF. The performance and feasibility of the proposed HDP-DPC-DPE for the 3L-ANPC AFE rectifier are verified by the simulation results.
