Maintain Real-Time High Power Factor Operation of the System
The BWSVG™ static var generator based on IGBT consists of three basic functional modules: detection module, control operation module, and compensation output module. The working principle is that the current information of the external CT detection system is analyzed by the control chip to determine the current information such as PF, S, Q, etc. The controller then provides a compensation drive signal, and the inverse circuit composed of the power electronic inverter circuit emits compensation current. It is suitable for industries such as metallurgy, coal, chemical, non-ferrous, petrochemical, semiconductor, and automotive.
