Difference between AC reactor and DC reactor | ATO.com

DC line reactor is used to limit AC component on DC to a specified value. Filter reactor, also called DC smoothing reactor, is used at DC side of converter. The current in line reactor is direct current with AC component. It is used to limit the AC component on direct current to one specified value.

DC reactors - Schaffner

The primary purpose of a DC reactor is to smooth the current pulses in DC circuits and to reduce the damaging harmonics on the power line. Schaffner DC reactors, also called DC link reactors or DC chokes, are typically connected to the semiconductors on the DC bus of converters, inverters and variable frequency drives (VFD).

FAQ: What is a VFD line reactor?

Aug 24, 2016 · A reactor can be referred to as either a line reactor or a load reactor, depending on where it's installed. A line reactor (also called an input reactor) is installed before the VFD and protects the drive, while a load reactor (also called an output reactor) is installed after the VFD and protects the motor.

Line Reactors and VFDs | EC&M

Fig. 2 shows reactors on the load side of single and multiple motors. Looking at the load side reactor from the motor view, the ability of the reactor to filter the waveform produced by the VFD improves the performance of both the motor and the total system. Summary of possible reactor performance.

Generator Exciters AC and DC Review - Engineers Edge

Industrial Electric Motors and Generators Menu Electric Generators Suppliers. Generator Exciters AC and DC Review. Generators require direct current to energize its magnetic field. The DC field current is obtained from a separate source called an exciter. Either rotating or static-type exciters are used for AC power generation systems.

The basics of variable frequency drive installation

Nov 18, 2016 · The VFD, often called an ac drive or inverter, takes a single- or three-phase signal and varies the speed of a three-phase ac induction motor. This is its main benefit. Running a motor more slowly can save significant energy, and speed changes may be useful to the application.

Line Reactors and AC Drives

In some rare cases where a strange motor configuration or a motor with 6 or more poles is used, the motor inductance may be too low and a reactor may be needed. Running multiple motors on one drive may also result in a low inductance load and the requirement of an output reactor. Reactors at the drive output to reduce the effect of reflected wave:

Mar 15, 2020 · What is a Line Reactor? A line reactor (also referred to as an electrical reactor or a choke) is a variable frequency drive (VFD) accessory that consists of a coil of wire that forms a magnetic field as current flows through it. This magnetic field limits the rate of rising of the current, thus reducing harmonics and protecting the drive from power system surges and transients.
