Abstract:
The present disclosure discloses a charging system, a charging method and a power adapter. The system includes a power adapter and a terminal. The power adapter includes a first rectifier unit, a switch unit, a transformer, a second rectifier unit, a sampling unit, a control unit and a first isolation 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 unit meets a charging requirement. The terminal includes a battery. When the terminal is coupled to the power adapter, the third voltage is applied to the battery.

Claim (Index 17):
A charging system for a terminal, comprising:\n a power adapter, comprising:\n a first rectifier unit, configured to rectify an input alternating current and output a voltage with a first pulsating waveform; \n a switch unit, configured to modulate the voltage with the first pulsating waveform according to a control signal; \n a transformer, having a primary winding and a secondary winding, and configured to output a voltage with a second pulsating waveform according to the modulated voltage with the first pulsating waveform; \n a second rectifier unit, coupled to the secondary winding, and configured to rectify the voltage with the second pulsating waveform to output a voltage with a third pulsating waveform; \n a first charging interface, coupled to the second rectifier unit; \n a sampling unit, arranged at a primary side of the transformer, and configured to sample voltage and/or current at the primary winding; \n a control unit, arranged at a secondary side of the transformer, 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 unit 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 voltage with the third pulsating waveform meets a charging requirement; \n and\n a first isolation unit, arranged between the control unit and the sampling unit, and configured to isolate a signal transmitted from the sampling unit to the control unit; \n and the 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 voltage with the third pulsating waveform to the battery when the second charging interface is coupled to the first charging interface.
