Title:
CHARGING SYSTEM, CHARGING METHOD, AND POWER ADAPTER
Document Type and Number:
WIPO Patent Application WO/2018/019155
Kind Code:
A1
Abstract:
The present disclosure discloses a charging system, a charging method, and a power adapter (1). The charging system includes a battery (202), a first rectifier (101), a switch unit (102), a transformer (103), a second rectifier (104), a sampling unit (106), and a control unit (107). The control unit (107) 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 (106), such that a third voltage with a third ripple waveform outputted by the second rectifier (104) meets a charging requirement. The third voltage is applied to the battery (202).
