The general intelligent contactor has a disadvantage of coil current pulsation. To overcome this disadvantage, a newtype intelligent control based on current feedback is innovatively applied in control and protective switch (CPS). The CPS with current feedback intelligent control module can not only keep the coil current smooth, but also improve the energysaving effect and reduce the power consumption. On this basis, a new method which can be used to simulate the dynamic characteristics of the electricmagnetic operating mechanism of CPS with current feedback intelligent control is proposed. The method builds a set of multifield equations, whose states are dynamically coupled with the feedback current signal and intertransform with time variation. The simulation result has a good agreement with the experiment result. The effects of hardware parameters on the performance of the control system of CPS are analyzed with the constructed model, and the hardware parameters are optimized by the analysis.
