摘要： A power supply device (200), a circuit control method and a power supply system (800), belonging to the field of power supply conversion technologies. The power supply device (200) can ensure that a second-stage transformation circuit (220) has a sufficiently high valley voltage by means of a valley-fill circuit (230) without using an electrolytic capacitor or other large-volume capacitors, thereby ensuring that the output voltage of the power supply device (200) is overall stable. On the other hand, the power supply device (200) can, by controlling the voltage at both ends of an energy storage unit in the valley-fill circuit (230), utilize the ability of the energy storage unit to store electric energy as far as possible whilst ensuring that the voltage does not exceed a voltage rating, so as to lower the requirements on the voltage resistance of the energy storage unit, thereby realizing the miniaturized design of the power supply device (200) and improving the portability of the power supply device (200).

摘要： A charging apparatus and a charging method are provided. The charging apparatus includes a boost circuit, a charging channel, and a communication control circuit. The boost circuit is configured to boost an output voltage of a power supply device. Through the charging channel, a boosted voltage is applied to a battery for charging. The communication control circuit is configured to communicate with the power supply device to instruct the power supply device to adjust the output voltage of the power supply device and/or an output current of the power supply device such that an output voltage of the boost circuit and/or an output current of the boost circuit matches charging requirements of the battery. According to the above technical solution, during charging of the battery, the output voltage of the power supply device and/or the output current of the power supply device is adjusted, such that the output voltage of the boost circuit and/or the output current of the boost circuit matches charging requirements of the battery. In this way, it is possible to reduce the need for voltage conversion in the boost circuit, which is possible to reduce heat generation of the boost circuit, thereby reducing heating of a device to-be-charged.
