Abstract :
The size of dc-bus capacitor is the key contributor for the volumes of PFC and battery charger, whose important characteristics is the 2nd order low-frequency ripple power on the DC bus. The motor in an electric vehicle can be used to store the ripple power, thus significantly reducing the size of the dc-bus capacitor. In this paper, a novel principle for Energy Storage in PFC by EV motor/generator is proposed. A digital controller is used to regulate the converter by using PWM, resulting in small volume, low noise and high power density. The size of the dc-bus capacitor is reduced 10 times.
