Abstract:
This paper applied the voltage control mode and the transformed buck circuit into the intelligent control of the ac contactor and realized closed-loop control. On this basis, a self-correction control scheme with the state capture circuit of main contacts has been proposed. This paper analyzed the principle of the self-correction control and realized it by current scanning. The control scheme can reduce the bounces of the ac contactor in making process with the offline self-correction. Through memory the offline self-correction parameters, the control module can recurrence the making coil current accurately. This control scheme relies less on the structure parameters of the ac contactor and is not sensitive to the input voltage fluctuation. The intelligent ac contactor can adjust the attractive force automatically and enhance the electrical life of the ac contactor. The complex modeling and simulation is not necessary during the optimal control. The experimental results verify the validity of the control scheme. ©2015 Chin. Soc. for Elec. Eng.
