最近 ,日本厂商研制成一种新型的节能变频器 ,其特点是在向电机供电时来检测其电能转换过程中的铁损和铜损 ,并控制两种损耗 ,使电能转换达到高效。这种节能变频器 ,与原来的定功率因数控制相比具有稳定性、适应性好的特点 ,即使遇到强烈的负荷变动也能正常运行。同时 ,该节能 Recently, Japanese manufacturers developed a new type of energy-saving inverter, which is characterized by detecting the iron loss and copper loss during the power conversion process when supplying power to the motor, and controlling the two types of losses so as to make the energy conversion efficient. This energy-saving inverter, compared with the original constant power factor control has the characteristics of stability, good adaptability, even in the face of strong load changes can be normal operation. At the same time, the energy saving
