    摘要： A device charging system and a device charging method and a power adapter are provided. The device charging system includes a power adapter and a device. The power adapter includes a first rectification unit, a switch unit, a transformer, a second rectification unit, a first charging interface, a sampling unit, and a control unit. The control unit is configured to output a control signal to the switch unit, and adjust a duty ratio of the control signal based on a voltage sampling value and/or current sampling value sampled by the sampling unit, whereby a voltage of a third pulsating waveform meets the charge requirements. The device includes a second charging interface and a battery. The second charging interface is coupled with the battery. When the second charging interface is coupled to the first charging interface, the second charging interface applies the voltage of the third pulsating waveform to the battery, whereby the voltage of the pulsating waveform output from the power adapter can be directly applied to the battery, which can achieve miniaturization and reduce the cost of the power adapter and improve the battery life.

    摘要： The present disclosure provides a power supply apparatus, a charging method, system storage medium. The power supply apparatus comprises a first-stage conversion circuit, a second-stage conversion circuit, and a valley-fill circuit. The first-stage conversion circuit is used for converting a rectified DC voltage to obtain a first DC voltage; the second-stage conversion circuit is used for converting the first DC voltage and outputting a second DC voltage, the second DC voltage being lower than the voltage value of the first DC voltage; the valley-fill circuit is used, if the second DC voltage is lower than a set value, for supplying power to the output end of the power supply apparatus so that the output voltage of the power supply apparatus is a constant DC voltage. The present disclosed technical solution is capable of reducing the size of a power supply apparatus.

    摘要： Disclosed are a device to be charged and a charging method. Said device comprises: a charging interface, a battery unit, a first switch unit, a second switch unit, a first control unit, and a second control unit. The first switch unit is connected to the second switch unit in parallel between the charging interface and the battery unit. When the first switch unit and/or the second switch unit is turned on, a charging path between the charging interface and the battery unit is turned on. The battery unit is charged by the voltage and the current input by the charging interface. The first control unit is used for, when the charging path between the charging interface and the battery unit needs to be turned on, controlling the first switch unit to be turned on. The second control unit is used for, when the first control unit controls the first switch unit to be turned on, controlling on or off of the second switch unit. The first control unit is further used for, when the charging path between the charging interface and the battery unit needs to be turned off, controlling the first switch unit and the second switch unit to be turned off.
