A brand-new simulation method for the intelligent AC contactor was proposed. The simulation method integrated the SPICE simulation of the control module with the dynamic simulation of the contactor and realized the closed-loop point-by-point co-simulation between the intelligent control module and the AC contactor. The underlying hardware circuit of the intelligent AC contactor can be designed in Multisim. And the dynamic model of AC contactor can be designed in LabVIEW. In addition, a two-way data channel has been built between Multisim and LabVIEW. Both of the softwares perform the nonlinear time-domain simulation simultaneously and independently, and exchange data at the end of each simulation time step so as to realize the co-simulation. The co-simulation system can find a reasonable control scheme for the intelligent AC contactor. At the same time, the digital control technology has been introduced and a current closed-loop control module for AC contactor was designed. The co-simulation and the digital control have been verified effectively.
