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 1):
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; a switch unit, configured to modulate the voltage with the first pulsating waveform according to a control signal; 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; 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; a first charging interface, coupled to the second rectifier unit, configured to apply the voltage with the third pulsating waveform 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, arranged at a primary side of the transformer, configured to sample voltage and/or current at the primary winding; 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; and 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.
