Inverters Play Crucial Role to Achieve Sustainable Society

摘要

Inverters are power conversion devices that convert direct current (DC) power into alternating current (AC) power. Inverters that are incorporated in home electric appliances, such as air conditioners and washing machines, as well as elevators and industrial robots, control the rotation speed of motors by adjusting the voltage and frequency of AC power. Inverters contribute to energy saving of motors in a wide range of fields. Motors are estimated to account for about 50 percent of total power consumption in the world. As the use of electric vehicles (Evs) become a global trend, the demand for motors and inverters continues to increase, signifying growing interests on energy savings.
