This paper presents a deadbeat predictive direct power control (DB-DPC) scheme for a fast battery charger to improve its dynamic

performance and stability. Recently, battery chargers have been adopting paralleled multi-leg converters based on silicon carbide

(SiC) devices to increase power capacity, which reduces the charging duration. However, the inherent instability of the battery is

regarded as a crucial issue during the fast charging process. Therefore, the proposed DB-DPC provides a stable steady state since it

includes real-time estimation of the variable battery impedance. Furthermore, the DB-DPC effectively minimizes the rising and settling

time, which demonstrates fast-dynamic response characteristics when compared to proportional–integral (PI) control. The control

performance is verified by various simulation and experimental results.
