摘要: 重频条件下电容器充电电源谐振电路由于谐振电容剩余电压的存在从而产生异常振荡，进而引发开关过流导致电源故障。针对这一问题，在分析谐振电路工作原理基础上，提出了在每个充电周期结束后，通过控制电源自身的部分开关导通，从而释放谐振电容剩余电压的解决方法，不仅可以让谐振电路趋于稳定，还避免了添加泄放电路的缺点，其控制方法也简单通用。对800 V/6 A的充电电源进行了电路仿真和实验验证，仿真和实验结果均表明,本文提出的方法可以在充电周期结束后将谐振电容上的剩余电压迅速归零，谐振电流也趋于稳定，有效抑制了谐振电路的异常振荡，从而验证了方法的有效性和实用性。Abstract: Under the condition of refrequency, the resonant circuit of the capacitor charging power supply oscillates abnormally due to the residual voltage, which leads to switching overcurrent and power failure. To address this issue, on the basis of analyzing the working principle of resonant circuit, we put forward a method of releasing the residual voltage of the resonant capacitor by controlling part of the switching of the power supply itself at the end of each charging cycle. The method not only keeps the initial voltage of the resonant capacitor at zero in each period, but also avoids the defect of adding the discharge circuit. The control method is simple and universal. The circuit simulation and experiment carried out on a 800 V/6 A charging power supply show that the proposed method reduces the residual voltage of the resonant capacitor to zero rapidly after the charging cycle, and the resonant current tends to be stable, which effectively inhibits the abnormal oscillation of the resonant circuit, thus verifying the effectiveness and practicability of the proposed method.
