Reactors for Inverter input, output, and DC-link
The line reactor for the variable frequency drive (VFD) has three types: input, output, and DC.
The input line reactor, also known as input reactor, is mainly used to limit the current surge caused by grid voltage fluctuation and operating overvoltage, effectively protecting the VFD and improving its power factor.
The output line reactor, also known as output reactor, is mainly used to compensate for the influence of distributed capacitance in long lines, suppress harmonic current, increase output impedance, effectively suppress dv/dt, and reduce high-frequency leakage current.
The DC reactor is connected between the rectification and inverter sections of the VFD system, and its main function is to improve the power factor of the VFD. It can stabilize the operation of the inverter and limit the short-circuit current.
BE has developed a three-in-one reactor that integrates input and output line reactors with a filter reactor. After application in the system, the harmonic current distortion rate can be reduced to below 5%‰/10%, and the filtering effect can meet the harmonic restriction of IEEE-519.
