摘要:
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).

An AC command voltage obtained by compensating a reference value of a commercial AC voltage output from a multiplication unit using an FB control unit is multiplied by k (0≦k≦1) by a multiplication unit and output to a first inverter control unit, and the remaining part is output to a second inverter control unit. The first and second inverter control units generate signals, based on command voltages obtained by superposing the AC command voltage from an AC output control unit on respective phase command voltages.

Preferably, when the control device (60) switches the selection switch (RY0), the control device controls inverters (20, 30) to achieve a balance between electric power generated in a first motor generator (MG2) and electric power consumed in a second motor generator (MG1).
