摘　　要：大功率接触器广泛应用于电动汽车和不间断电源系统等多个领域,具有可靠性高、使用寿命长的优点。传统的驱动方式导致接触器线圈耗电发热严重,限制了其推广应用,因此接触器的节能驱动电路设计是目前研究的热点。对国内外现有的节能驱动电路进行归纳总结,确定各方法的优缺点。由于有限元商用软件在电路建模上存在局限性,通过电路仿真软件与有限元软件联合仿真的方式实现磁场-电路一体化建模。通过使用基于PWM控制的节能驱动电路,最终线圈功耗降低80%,有效地减少了能源损耗与温升,对接触器节能驱动电路设计具有较好的指导与借鉴意义。High-power contactors that have the advantages of high reliability and long service life are widely used in electric vehicles and uninterruptible power supply systems.The traditional driving methods lead to consumption of a lot of power and rising of temperature,which limits its application.Therefore,the energy-saving driving circuit design of the contactor is the research focus currently.This paper summarizes the existing energy-saving driving circuits at home and abroad.Due to the limitations of finite element commercial software in circuit modeling,the paper built the magnetic field-circuit integration model by co-simulation of circuit simulation software and finite element software.By using an energy-saving driving circuit based on PWM control,the coil power consumption is reduced by 80%,effectively reducing energy consumption and temperature rise.It has a good guidance and reference significance for the energy-saving driving circuit design of the contactor.
