Title:
CHARGING SYSTEM FOR TERMINAL, CHARGING METHOD, AND POWER SUPPLY ADAPTER
Document Type and Number:
Japanese Patent JP2018153093
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a charging system for a terminal, so that a power supply adapter outputs a second AC satisfying a charging request and applying the second AC directly to a battery of the terminal.SOLUTION: A charging system includes a power supply adapter 1 and a terminal 2. The power supply adapter includes a first rectifier unit 101, a transformer 103, a composite unit 104, a first charging interface, a sampling unit 106, and a modulation control unit 100. The modulation control unit modulates a voltage of a first ripple waveform based on a voltage sampling value sampled by the sampling unit to output a second AC satisfying a charging request, from the composite unit. The terminal includes a battery 202 connected to a second charging interface. When the second charging interface is connected to a first charging interface, the second charging interface applies the second AC to the battery, and a voltage of an AC waveform output from the power supply adapter is applied directly to the battery.SELECTED DRAWING: Figure 1A
