Abstract:
The present disclosure discloses a charging system, a charging method, and a power adapter. The charging system includes a battery, a first rectifier, a switch unit, a transformer, a second rectifier, a sampling unit, and a control unit. The control unit outputs a control signal to the switch unit, and adjusts a duty ratio of the control signal according to a current value and/or voltage value sampled by the sampling unit, such that a third voltage with a third pulsating waveform outputted by the second rectifier meets a charging requirement. The third voltage is applied to the battery.

Claim (Index 1):
A power adapter, comprising:\n a first rectifier, configured to rectify an input alternating current and output a first voltage with a first pulsating waveform; a switch unit, configured to modulate the first voltage according to a control signal and output a modulated first voltage; a transformer, having a primary winding and a secondary winding, and configured to output a second voltage with a second pulsating waveform according to the modulated first voltage; a second rectifier, coupled to the secondary winding, and configured to rectify the second voltage to output a third voltage with a third pulsating waveform; a first charging interface, coupled to the second rectifier, configured to apply the third voltage to a battery in a terminal via a second charging interface of the terminal when the first charging interface is coupled to the second charging interface, in which the second charging interface is coupled to the battery; a sampling unit, configured to sample voltage and/or current at the primary winding; and a control unit, coupled to the sampling unit and the switch unit respectively, and configured to output the control signal to the switch unit, to calculate a voltage sampling value and/or a current sampling value corresponding to an output of the second rectifier according to a voltage value and/or a current value sampled by the sampling unit, and to adjust a duty ratio of the control signal according to the current sampling value and/or the voltage sampling value such that the third voltage meets a charging requirement of the battery of the terminal.
