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 adopt paralleled multi-leg converters based on silicon carbide (SiC) devices to
increase the power capacity, and thus reduce 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 because it
includes the real-time estimation of the variable battery impedance. Furthermore, DB-DPC effectively minimizes the rising and
settling time, which demonstrates fast-dynamic response characteristics as compared to proportional-integral (PI) control. The
control performance is verified by various simulation and experimental results.
