Abstract
A charging system for improving a power factor and a current quality in a grid stage is provided. The charging system includes a rectifying circuit that is configured to rectify a grid power and a converter that is configured to receive a voltage-current rectified by the rectifying circuit and convert the voltage-current into a charge voltage-current to be provided to a battery. A capacitor is connected across a connection end of the rectifying circuit and the converter. The converter includes a first high frequency switching circuit, a transformer, and a second high frequency switching circuit.
