Original Abstract Submitted
a charging device includes: a plurality of legs including respective upper and lower arms having respective switching elements, the upper and lower arms being connected to a battery and a negative pole of a dc charger, respectively; a motor having three phases with a neutral point connected to a positive pole of the dc charger; a driver that drives the switching elements with respective pwm signals; and a controller that monitors a current from the legs to the battery, and instructs the driver to apply duty ratios of the pwm signals so that a fluctuation width of the monitored current is reduced. further, the controller monitors the measurement result of the sensor at a period other than 1/n of a period of a carrier of the pwm signals, where n is a number of the plurality of legs used for charging the battery.
