This paper presents the analysis and design of a multiphase $\boldsymbol{LC}_{p}\boldsymbol{C}_{s}$ resonant converter suitable for high-current low-voltage battery charger applications. In order to reduce the conduction loss, the inverter stage of the converter is obtained from the parallel connection of $\boldsymbol{N}$ class $\mathbf{D}\boldsymbol{LC}_{p}\boldsymbol{C}_{s}$ resonant inverters. The effect of the leakage inductance of the transformer on the resonant tank is evaluated. The output stage is based on a multi-winding current multiplier, obtained from the parallel connection of $\boldsymbol{M}$ current-doubler rectifiers. The regulation of the charging current is implemented at constant frequency by modifying the phase displacement of the output voltage of each class D section. The converter is designed for charging high-performance Absorbent Glass Mat (AGM) batteries with a current modulated from 20 A down to 1 A. The maximum voltage is limited to 14.4 V. |
