A charging system (3) is provided for charging a chargeable battery (80, 90). The charging system (3) includes a phase-shifting transformer (T 1 ) and a converting unit (31). The phase-shifting transformer (T 1 ) includes a three-phase primary winding assembly (Np) and plural three-phase secondary winding assemblies (N s ). After a three-phase AC input voltage (V in ) is received by the three-phase primary winding assembly (Np), the three-phase AC input voltage (V in ) is decreased, so that plural three-phase AC output voltages (V out ) are outputted from respective three-phase secondary winding assemblies (N s ). Moreover, there is a phase-shifting angle between any two of the plural three-phase AC output voltages (V out ). The converting unit (31) is electrically connected with the phase-shifting transformer (T 1 ), and includes plural three-phase rectifying circuits (310, 410, 510) and a DC-DC converting circuit (311, 411, 511). The plural three-phase AC output voltages (V out ) are rectified by the three-phase rectifying circuits (310, 410, 510), and the rectified voltage is converted into a DC charging voltage (V c ) to charge the chargeable battery (80, 90). |
