摘　　要：在对交流接触器能耗进行分析的基础上,根据交流接触器可用强激磁吸动和弱激磁吸持的特点,将其电磁系统的交流运行方式改为直流运行方式,采用自转换式改变占空比的节能方案,设计开发了一款智能型交流接触器节能专用集成电路芯片ZDLX。此芯片采用0.5μm混合信号CMOS工艺。实测结果表明,此芯片配合交流接触器使用后可将后者功耗降低90%(仅为原功耗的10%)。因此该节能专用芯片ZDLX具有重要的社会和经济价值。This paper analyzes the power consumption of AC contactor,according to AC contactor＇s characteristics of strong magnetic to pull in and weak magnetic to hold, changing the electromagnetic system form AC operation mode to DC, using the technology of changing the duty cycle automatically, we develop and design an intelligent energy saver ASIC chip ZDLX for AC contactor. The chip fabricated in a 0.5 I^m mixed-signal CMOS process of Shanghua in wuxi. The test results confirmed that out- put signals of the chip meet the design requirements, and the power consumption of AC contactor decline almost 90% （10% of the original ）with the chip and application circuit. Therefore, ZDLX has important economic and social benefit.
