DC link reactor chokes

V&T EcoDriveCN® DC reactors are an economical means of filtering and controlling the DC bus voltage and current in AC drive (frequency inverter).

Install V&T EcoDriveCN® DC link reactor when the power supply capacity is 500 kVA or more and the power supply capacity is 10 times or more than that of the inverter's capacity, or when a distortiongenerating source such as a thyristor or a large-capacity inverter is connected to the same wiring leads.

V&T EcoDriveCN® DC link chokes help reduce AC input line current harmonic distortion while absorbing DC bus voltage spikes.

V&T EcoDriveCN® DC link chokes add protection and filtering but should not be considered a direct alternative to AC input or output reactors.

Why use V&T EcoDriveCN® DC reactor?

• Reduction in harmonics


• Improved power factor


• Help meet IEEE-519 limits


• Absorb voltage/current spikes


• Reduce peak input current


• Reduce AC ripple on DC bus


• Reduce dv/dt and di/dt rates


• Solve nuisance over-voltage tripping


• Reduce DC Bus transient over-voltage

V&T EcoDriveCN® DC reactors smooth the current pulses in DC circuits.

V&T EcoDriveCN® DC link chokes are suitable for such applications: AC PWM inverters/drives, DC to AC inverters, variable frequency motor drives, clectrical vehicle controllers.



V&T EcoDriveCN® AC input choke reactors are best-in class power quality units with a long history of proven performance. Rugged and robust, they are unequalled in absorbing power line disturbances that can damage or shut down AC variable speed drives (VSD, frequency inverters) and other sensitive equipment.
