An adaptive zero-crossing switching technology for intelligent power capacitor based on closed loop control of zero voltage was presented.Analog circuits were applied for catching zero point of voltage and feeding back switching time.The drive circuits of magnetic latching relay were improved so that its action time has greater consistency.By simplifying the process of sampling and calculating,the stability and accuracy of adaptive control have been improved.The experimental results show that this technology has a stable and reliable effect on adaptive control as well as the result of limiting the inrush current of switching power capacitor.
