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 19):
A charging system, comprising:\n 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; \n a switch unit, configured to modulate the first voltage according to a control signal and output a modulated first voltage; \n 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; \n 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; \n a first charging interface, coupled to the second rectifier; \n a sampling unit, configured to sample voltage and/or current at the primary winding; and \n 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, \n a terminal, comprising a second charging interface and a battery, the second charging interface being coupled to the battery, wherein the second charging interface is configured to apply the third voltage to the battery when the second charging interface is coupled to the first charging interface.
