Description

控制充电的方法和装置以及电子设备 技术领域
本发明实施例涉及通信领域，并且更具体地，涉及控制充电的方法和装置以及电子设备。
背景技术
随着电子设备(例如智能手机)的普及，电子设备的充电问题成为供应商重点关注的问题。现有的电子设备可以采用高压充电模式或低压充电模式进行充电。图1示出了电子设备100的电路示意图，其中，该电子设备100支持以高压充电模式进行充电。该电子设备100可以包括充电接口110、电池140以及设置于充电接口110和电池140之间的充电电路120和控制电路130，其中，该充电电路120可以称为BUCK电路，主要包括：金属氧化物半导体(Metal-Oxide-Semiconductor Field Effect Transistor，MOSFET)管1(MOSFET-1)、MOSFET管2(MOSFET-2)、电感和电容，其中，在充电过程中，该MOSFET-1和MOSFET-2可以交替处于导通状态。
图2示出了另一个电子设备200的电路示意图，其中，该电子设备200可以包括充电接口210、电池240以及设置于充电接口210和电池240之间的充电电路220和控制电路230，与图1不同的是，该电子设备200支持以低压充电模式进行充电，相应地，该充电电路220包括MOSFET管3(MOSFET-3)和电容，其中，在充电过程中，MOSFET-3可以一直处于导通状态。
