    摘要: A high-voltage battery charging system includes a rectifier circuit, a power factor correction circuit, a bus capacitor, an intermediate non-isolated DC-DC converting circuit, an intermediate output capacitor, and a non-isolated DC-DC converting circuit. The rectifier circuit is used for rectifying an AC input voltage into a rectified voltage. The power factor correction circuit is used for increasing a power factor of the rectified voltage and generating a bus voltage. The bus capacitor is used for energy storage and voltage stabilization. The intermediate non-isolated DC-DC converting circuit is used for boosting the bus voltage into an intermediate output voltage. The intermediate output capacitor is connected between an output terminal of the intermediate non-isolated DC-DC converting circuit and the common terminal COM for energy storage and voltage stabilization. The non-isolated DC-DC converting circuit is used for converting the intermediate output voltage into a high charging voltage, thereby charging the high-voltage battery unit.

    摘要: The invention relates to an inrush current protection circuit for a power supply. The power supply includes a rectification circuit coupled to a main body of the power supply through an energy-storage capacitor. The main body of the power supply is provided with a reference voltage, and the setup time of the reference voltage is greater than a threshold value. The inrush current protection circuit includes a current limiting resistor coupled between a negative terminal of the rectification circuit and a ground terminal of the energy-storage capacitor for preventing the generation of an inrush current the instant that the power supply is powered on, and a switch coupled in parallel with the current limiting resistor and which is controlled by the reference voltage. When the reference voltage is set up, the switch switches from an open state to a short state, so as to bypass the current limiting resistor.
