According to one embodiment, a vehicle drive system has an engine to generate torque. The vehicle drive system has an alternator coupled to the engine. The alternator converts torque from the engine to magnetic flux and generate an AC voltage. The vehicle drive system has a PWM converter coupled to the alternator to convert AC voltage from the alternator to DC voltage. The vehicle drive system has a PWM inverter which is connected with the PWM converters, the PWM inverter is to transform DC voltage to AC voltage. The vehicle drive system has a filter capacitor between the PWM converter and the PWM inverter. The filter capacitor is configured to be charged by the PWM converter. |
