Research on Energy Saving Power Supply Conversion Module for AC Contactor

摘要: 针对交流接触器的节能问题，设计了一种交流接触器节能电源转换模块。节能电源转换模块将输入的交流电整流后变为直流电输出至接触器电磁线圈，通过电子技术对大、小电流进行控制分别实现接触器电磁线圈的启动吸合和保持吸合，节省了保持吸合的能量。节能电源模块应用于交流接触器后可改善动力特性、无铁损、延长使用寿命，节能效果显著。

Abstract: For the AC contactor’s energy saving issues, an energy saving power supply conversion module was designed. The energy saving power supply conversion module can convert the input alternating current into the direct current and output to electromagnetic coil. Control the electric current’s magnitude by the means of the electronic technique to realize the start pull-in and hold pull-in of the AC contactor’s electromagnetic coil. It can save the energy of hold pull-in. When the energy saving power supply conversion module was applied to the AC contactor, it could improve the dynamic characteristics, had no iron loss, increased the service life, and had an outstanding effect of energy saving.
