FAQ

Q1: Where are DC reactors installed?

DC link reactors are typically installed on the DC bus (DC Link) between the rectifier and inverter. Inside a frequency converter (VFD), DC reactor is located between the rectifier bridge output and the DC capacitor; some designs also connect it in series in the DC bus circuit. Simply put, DC line reactor is the intermediate link between AC-to-DC and DC-to-AC conversion, used to regulate and optimize the DC-side current.

Q2: How do DC reactors improve power quality?

Dual DC link reactors, through their inductive characteristics, can suppress the rate of change of current (di/dt), effectively reducing ripple current in the DC bus. Simultaneously, they reduce harmonic propagation to the grid side, improving the input current waveform to be closer to a sine wave. Furthermore, DC link chokes limit inrush current and surge current, reducing the impact on the rectifier and capacitor, thus improving overall system stability and power quality.

Smoother Motor Operation and Less Electrical Noise

Installed this 2HP DC reactor on a small conveyor system at work, and the difference was immediate. The annoying electrical noise that used to mess with our nearby sensors is pretty much gone, and the motor starts much smoother without those sharp current spikes. It's compact, easy to mount, and feels solid. For the price, it's a cheap and effective upgrade for any VFD setup. Highly recommend if you're dealing with harmonic issues or just want to extend the life of your drive components
