Abstract
A charging system, a charging method, and a power adapter are provided. The power adapter includes a battery, a first rectification unit, a transformer, a synthesis unit, a first charging interface, a sampling unit, and a modulation and control unit. The modulation and control unit is configured to modulate a voltage of a first pulsating waveform according to a voltage sampling value obtained by the sampling unit, such that a second AC output from the synthesis unit meets charging requirements.
