The invention discloses a bidirectional wireless charging control method, and the method comprises the following steps: S1, obtaining an output voltage value Uo *, judging whether forward charging is carried out or not at the same time, entering a step S2 if the forward charging is carried out, and entering a step S3 if the forward charging is not carried out; s2, setting the phase difference theta of the output voltage between the primary side converter and the secondary side converter to be equal to pi/2, and entering step S4 after setting is completed; s3, the phase difference theta of the output voltage between the primary side converter and the secondary side converter is set to be equal to-pi/2, and the step S4 is executed after setting is completed; s4, system power transmission is started, and the actual value Uo of the output voltage is tested; s5, calculating a difference value U = Uo *-Uo between the actual value of the output voltage and the required value of the output voltage; s6, inputting the calculated voltage difference value U into a PI controller of the secondary side, and performing PI adjustment through the PI controller; and S7, calculating the phase shift angle beta of the secondary side converter at the current moment, and transmitting the phase shift angle beta value to the primary side through the wireless communication device.

    本发明公开了一种双向无线充电控制方法,所述方法包括如下步骤:S1:获取输出电压值Uo*,并同时判断是否为正向充电,若是正向充电则进入步骤S2,若不为正向充电则进入步骤S3;S2:设置原边和副边变换器之间输出电压的相位差θ=π/2,完成设置后进入步骤S4;S3:设置原边和副边变换器之间输出电压的相位差θ=‑π/2,完成设置后进入步骤S4;S4:启动系统功率传输,测试输出电压的实际值Uo;S5:计算输出电压实际值与输出电压需求值之间的差值△U=Uo*‑Uo;S6:将计算得到的电压差值△U输入副边的PI控制器,通过PI控制器进行PI调节;S7:计算当前时刻副边变换器的移相角β,并通过无线通信装置将移相角β值传送给原边。
