The invention provides a charging pile, a power module and a control method thereof.The control method comprises the steps that in the starting stage, an AC/DC control module in the power module is controlled firstly, and starting is conducted according to the load state of the power module; and after the AC/DC control module is started, the AC/DC control module is controlled to operate in a continuous working mode in various load states, so that ripples of direct-current output voltage of the power module during no load and light load are reduced, the direct-current output problem of the system is reduced, the working performance of the power module is improved, and the corresponding charging pile meets the industrial standard requirement. Moreover, the AC/DC control module can be stably switched from a hiccup mode to a continuous working mode, and the violent fluctuation of the bus voltage is eliminated.

    本申请提供一种充电桩、功率模块及其控制方法,该控制方法在启动阶段,先控制功率模块中的AC/DC控制模块,根据功率模块的负载状态进行启动;然后在AC/DC控制模块完成启动后,控制AC/DC控制模块在各种负载状态下均运行于连续工作模式,以降低空载以及轻载时功率模块直流输出电压的纹波,减少系统直流输出问题,改善功率模块的工作性能,使得相应充电桩满足行业标准要求。而且还可以使得该AC/DC控制模块平稳的从打嗝模式切换到连续工作模式,消除母线电压的剧烈波动。
