A line reactor (also referred to as 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 rise of the current, thus reducing harmonics and protecting the drive from power system surges and transients. There are two primary types of reactors used in variable frequency drives: AC & DC. When an AC reactor is placed between the power system and the drive, it is referred to as an AC line reactor. When a DC reactor is inserted into the DC link of a variable frequency drive, it is known as a DC link reactor.

Buck-boost transformers are small single phase transformers designed to reduce (buck) or raise (boost) line voltage from 5-20%. The most common example is boosting 208 volts to 230 volts, usually to operate a 230 volt motor such as an air-conditioner compressor, from a 208 volt supply line. Buck-boosts are a standard type of single phase distribution transformers, with primary voltages of 120, 240 or 480 volts and secondaries typically of 12, 16, 24, 32 or 48 volts. They are available in sizes ranging from 50 volt amperes to 10 kilo-volt amperes. Buck-boost transformers are shipped ready to be connected for a number of possible voltage combinations.

A stifle (or line reactor) is a curl of wire around an attractive center that makes an attractive field when current moves through it. This attractive field expands the impedance of the line and lessens the absolute consonant substance infused from the drive onto the Line chokes are used for di/dt controlling ( Rate of Rise of Current ). Harmonic Control, P.F. Control, Supressing the Spikes & Surges. Line Communicating Chokes made as per the specific requirement of the clients. Line Reactor Choke is used to provide better protection against over voltage on the line supply. These are widely applicable in in Systems like Battery Chargers, AC DC drives, UPS.
