摘要: 根据大容量能库型装置双极性充电电源对采样电路的高鲁棒性、正负极性均可控等要求，研制了一种隔离电压大于30 kV、隔离转换电压误差小于0.1%的正负双极性直流高压隔离采样电路。采用电压/频率、频率/电压转换方法，通过光纤、变压器隔离等措施，实现了正负双极性直流高压同时隔离采样，解决了目前双极性直流高压电源存在的正负极性电压不平衡、控制信号与高功率系统地隔离不完全问题，提高了电源的抗电磁干扰能力。该电路在±10 kV双极性充电输出时，正负极性电压偏差小于0.1%，100多台充电电源在18.3 MJ脉冲装置放电产生的复杂电磁干扰环境下可靠稳定运行。Abstract: According to the requirements of high robustness and positive and negative polarity controllability of the sampling circuit for bipolar charging power supply designed for a large capacity energy storage device, a positive and negative bipolar DC high-voltage isolation sampling circuit with isolation voltage ≥ 30 kV and conversion voltage fractional error ≤ 0.1% has been developed. The voltage/frequency and frequency/voltage conversion methods were adopted, integrated with optical fibers, transformer isolation and other measures, the positive and negative bipolar DC high voltage were isolated and sampled independently at the same time. The problems of the bipolar DC high voltage power supply, such as the voltage imbalance of positive and negative polarity, the incomplete isolation of ground wires between the control signal system and the high power system, and so on were solved. The EMI resistance of the power supply was improved. As the bipolar charging voltage output achieved ± 10 kV, the deviation of positive and negative polarity voltage is less than 0.1%. More than 100 chargers operated reliably and stably under the complex electromagnetic interference environment generated by discharge of the 18.3 MJ pulsed device.
