FAQ

Q1: Do solar/wind power systems need DC reactors?

In solar and wind power systems, DC link chokes are generally necessary. They suppress high-order harmonics caused by current fluctuations, improve the power factor, and protect capacitors and modules in the inverter from surge currents, thereby reducing equipment failure rates.

Q2: Why use a DC Link Reactor?

DC smoothing reactor acts as a buffer and filter in the circuit. Compared to AC reactors, it does not cause voltage drops, smooths the DC waveform, ensures stable operation of the inverter stage, and resists high current surges during grid voltage dips, protecting the upstream rectifier.

Smooth Current Control for My VFD Pump

I’m using this 10HP DC reactor with a VFD pump, and it’s been working well. It helps smooth the current and reduce harmonics without adding much noise. The silicon steel core feels well built, and mounting was straightforward. Since installing it, the inverter system has been running more consistently, and I’m hoping it helps with capacitor life as well.
