摘　　要：针对大容量交流接触器的运行特点提出了电流闭环控制思路,并进行了控制方案的设计与实验验证;在量大面广的中小容量接触器领域,设计了一种集成化的控制方案。该方案具有体积小、性价比高的特点;同时还设计了一款低电压控制模块,通过前级升压电路和后级斩波电路的共同作用,解决了在低电压情况下的智能控制问题,以满足智能接触器电磁机构宽电压、交直流运行的要求。最后,阐述了一种新型组合式智能接触器的控制技术。This paper elaborated the control principle and control strategy of the intelligent contactor cun＇ent closed-loop control technology and earned on experiments of a prototype according to the operation characteristics of large capacity of AC contactor. Integrated closed-loop control scheme was proposed for medium and small capacity contactor ,and the control module has advantage of small volume, high cost performance, etc. Meanwhile the low voltage control module with combined action of the boost circuit and chopper circuit, was designed to solve intelligent control problems of low voltage, to meet wide voltage of electromagnetic system and AC/DC operation characteristics of the intelligent contactor. In the end, the paper introduced a new type of combination intelligent contactor control technology.
