3Ph / 1Ph AC & DC Chokes & Inductors for Harmonic Filtering
Modern power electronics are vulnerable to harmonic distortion, voltage transients, and electromagnetic interference (EMI). Whether used in inverters, UPS systems, or VFDs, installing the right AC or DC choke ensures smoother current flow, better efficiency, and longer equipment life.
At Rishab Industries, we design and manufacture a wide range of 1Ph and 3Ph AC & DC chokes—optimised for filtering, current smoothing, surge suppression, and THD reduction. Engineered using high-grade CRGO or CRNGO, and available in copper or aluminium windings, our inductors ensure reliability across a broad range of industrial and commercial applications.

Frequently Asked Questions (FAQs)
What is the difference between an AC and DC choke?
AC chokes suppress voltage spikes and harmonics in AC lines, while DC chokes filter ripple and stabilize current in DC links of inverters and UPS.
Where are 3-phase chokes used?
In 3-phase UPS, VFDs, solar inverters, and automation panels—typically for current smoothing and protection from line disturbances.
Do these chokes reduce harmonics?
Yes. They help reduce THD and suppress electrical noise, improving power factor and equipment life.
Can I customize the inductance value?
Absolutely. Rishab offers complete customization for inductance, current, voltage, and enclosure type.
Are copper and aluminum both available?
Yes. You can choose copper or aluminum windings based on cost, efficiency, and thermal behavior.
