Abstract

Normal starting will have a great impact on the power grid and the equipment, and thyristor startup will reduce the torque. This is a common problem in industrial production. This article introduces the application of variable frequency technology in the startup of high-power motors. And the derivation shows that the three frequency conversion technologies have the advantages of high total power and low harmonic components compared to the traditional single-phase frequency conversion. Based on this, the discrete frequency conversion technology is demonstrated. The calculation shows that the discrete frequency conversion technology can reduce the starting current. It has the advantages of shock without loss of torque. At the same time, this paper also shows through calculation that it is impossible to achieve safe speed regulation only by adjusting the frequency. It must cooperate with voltage control. Frequency conversion technology can better solve the control problem, and achieve stepless speed regulation and automatic servo. Is of great significance. On the basis of these calculations, this article also looks forward to the application of future frequency conversion technology.
