The invention provides a voltage stabilization method for a wireless charging system, and the method comprises the steps: obtaining the charging information of the wireless charging system, and judging whether a preset charging condition is met or not according to the charging information; if the preset charging condition is not met, judging whether a DC/DC converter in the wireless charging system reaches a voltage regulation limit or not; if the DC/DC converter does not reach the voltage regulation limit, driving a DC/DC converter to regulate the charging voltage through a controller; and ifthe DC/DC converter reaches the voltage regulation limit, driving the three-phase rectification module by the controller to regulate the charging voltage. Whether the charging voltage meets the preset charging condition or not is analyzed through the controller, then the DC/DC converter and the three-phase rectification module are controlled to adjust the charging voltage, direct or indirect voltage stabilization control over the charging voltage output by the wireless charging system is achieved, the charging requirement of the storage battery is met, and the charging efficiency of the storage battery is improved.

    本发明提出了一种无线充电系统的稳压方法,包括:获取无线充电系统的充电信息,根据充电信息判断是否满足预设充电条件;若不满足预设充电条件,判断无线充电系统中的DC/DC转换器是否到达调压极限;若未到达调压极限,通过控制器驱动DC/DC转换器调整充电电压;若到达调压极限,通过控制器驱动三相整流模块调整充电电压。通过控制器分析充电电压是否满足预设充电条件,进而控制DC/DC转换器和三相整流模块对充电电压进行调整,实现了对无线充电系统输出的充电电压直接或间接的稳压控制,以满足蓄电池的充电需求,提高蓄电池的充电效率。
