Abstract:
Commercial AC voltage applied to an input terminal (90) from a commercial power supply external to the vehicle is boosted by a transformer (86) to a voltage level higher than the voltage (VB) of an electricity storage device (B) to be applied to neutral points (N1, N2). In a charging mode of the electricity storage device (B) from a commercial power supply, all npn transistors of an inverter (20, 30) are turned off. The AC voltage applied to the neutral points (N1, N2) is rectified by an anti-parallel diode of the inverter (20, 30) to be supplied onto a power supply line (PL2). A boost converter (10) controls the charging current from the power supply line (PL2) towards the electricity storage device (B).
