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 15):
The power adapter according to  claim 14 , wherein the control unit is further configured, before determining whether there is the poor contact between the first charging interface and the second charging interface, to receive information indicating a path impedance of the terminal from the terminal,\n the control unit is configured to send a fourth instruction to the terminal, in which the fourth instruction is configured to query a current voltage of the battery in the terminal; the control unit is configured to receive a fourth reply instruction sent by the terminal, in which the fourth reply instruction is configured to indicate the current voltage of the battery in the terminal; the control unit is configured to determine a path impedance from the power adapter to the battery according to an output voltage of the power adapter and the current voltage of the battery; and the control unit is configured to determine whether there is the poor contact between the first charging interface and the second charging interface according to the path impedance from the power adapter to the battery, the path impedance of the terminal, and a path impedance of a charging wire between the power adapter and the terminal.
