Because the basic principle of frequency the inverter is to provide a voltage-regulated FM power supply for the asynchronous motor to meet energy saving or process requirements, it has three parts: rectification, DC and inverter. If the external voltage is unstable, the DC voltage will drop, so that the inverter part cannot continuously output the set voltage level, which causes the inverter protection to stop.

In the industrial field, frequency inverter and motor installation distance can be roughly divided into three situations: source distance, distance and near distance. 20m within close range, 20-100m in the distance, more than 100m distance.
Studies show that up to 80 percent of the energy from the power source to the industrial consumer is lost through the transition of raw material to the point of useful output—much of that at the point of conversion from electrical to mechanical output.
