Overview

This single-phase DC reactor, with a capacity of 75hp, can be used in 3-phase VFDs, smoothing current and limiting inrush current. The DC choke for vfd uses a silicon steel core, providing strong anti-saturation capability. It effectively reduces DC ripple current, suppresses harmonics, and improves system stability.

Feature

Smooths DC current, making the current waveform on the DC side more stable.
Improves the power factor, enhancing the system's energy utilization efficiency.
Suppresses DC side harmonic currents, reducing harmonic interference to the power grid and equipment.
Enhances the rectifier's operational stability, ensuring reliable rectification.
Reduces DC bus voltage fluctuations, providing a stable power supply for downstream equipment.
Protect the inverter from DC-side current surges. Improve motor operating performance and make motor operation smoother.

FAQ

Q1: How to select the inductance of a DC reactor?

The inductance should be selected based on the inverter's power, voltage, and allowable DC ripple. Generally, the inductance should control the DC ripple to around 5%-10%. Higher power or greater requirements for current stability necessitate a larger inductance, but excessive inductance may cause voltage drop or slower response.

Q2: What is the DC reactance ratio?

The DC reactance ratio is the ratio of the DC line reactor's voltage drop to the DC bus voltage. General reference values:

Small power VFD: 2%-3%
Medium power VFD: 3%-5%
High power VFD: 5%-7%

A balance must be struck between ripple suppression and voltage stability when selecting the inductance.
