针对电网低压侧无功补偿装置结构复杂以及投切时存在大量涌流等问题，采用过零点投切技术，研制开发了具有高集成、无涌流和低成本等优点的新型智能低压电容器。利用MATLAB对不同残压下投入电容器的系统模型进行了仿真，并与实际应用中电网电压为零时投入电容器的实验结果进行分析比较。结果表明，晶闸管两端电压过零时投入电容器无涌流。

According to the complex structure of reactive power compensation device on the low voltage side and existing a large amount of flashy flow , a new intelligent low voltage capacitor of high integration , without the freshness and the low cost has been developed based on the technology of zero-crossing switching .The system model of switching capacitor under different residual voltage are simulated .Compared to the experimental results of inputting with zero net-work voltage:the flashy flow is low with zero voltage of thyristor .
