FAQ

Q1: What is a DC reactor used for?

A DC reactor is primarily used in DC circuits to smooth DC current, reduce current ripple, and suppress harmonic interference by increasing inductance. It reduces the impact of current fluctuations on power electronic equipment, thereby improving system stability and reliability. DC smoothing reactors are commonly used in frequency converters, rectifiers, inverters, and motor drive systems to improve power quality and protect critical electronic components.

Q2: What is the role of a DC reactor in a frequency converter?

In a frequency converter system, a DC link reactor is typically installed between the rectifier bridge and the DC bus. It limits the rate of current change, reduces harmonic currents generated by the rectifier, and reduces the impact on filter capacitors and rectifier modules. By smoothing DC current and reducing current fluctuations, DC reactor for VFDs improve the stability of the frequency converter system, reduce equipment heat generation, and extend the lifespan of the frequency converter and related electrical components.

Cool, Quiet, and Harmonics-Free

Cleaned up my VFD harmonics and stopped tripping breakers – runs cool and quiet exactly what my 3HP motor needed.
