CHARGE CONTROLLER AND VEHICLE WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a charge controller that reduces switching noise generated when an energy storage device loaded on a vehicle is charged from an external AC power supply.

SOLUTION: When charging the energy storage device B from the external AC power supply 60, power is supplied to neutral points N1 and N2 of motor generators MG1 and MG2 from the external AC power supply 60 through a power supply plug 50 and power lines NL1 and NL2. ECU 30 PWM-controls only a U-phase arm 22 and turns off upper/lower arms of a V-phase arm 24 and a W-phase arm 26 in an inverter 20. ECU 30 alternately turns on upper/lower arms in accordance with polarity of the external AC power supply 60 without performing PWM control in an inverter 10.
