Abstract
A charging system, a charging method, and a power adapter are provided. The power adapter includes a first rectification unit, a switch unit, a transformer, a second rectification unit, a first charging interface, a sampling unit, and a control unit. The control unit is configured to output a control signal to the switch unit, and adjust a duty ratio of the control signal based on a voltage sampling value and/or a current sampling value sampled by the sampling unit, in which a voltage of a third pulsating waveform output from the second rectification unit meets the charging requirements. The terminal includes a second charging interface and a battery. The second charging interface is coupled with the battery. When the second charging interface is coupled to the first charging interface, the second charging interface applies the voltage of the third pulsating waveform to the battery.
