* TCI KLR series three phase AC line reactors are intended for use as input filters for adjustable speed DC drives and as input or output filters for AC-PWM variable frequency drives. Drive performance is significantly improved, the drives input rectifier is protected from failure or damage, and drive harmonic demands are tamed with the addition of a K-rated line reactor. KLR line reactors act as interface buffers between solid state power circuits and the line or the motor. (Not unlike the surge protector for your desk-top PC). All drives, in any application, will benefit when applied with KLR series line reactors.
* Drives are susceptible to problems caused at their interface to the line or motor. Some of these issues include AC voltage waveform line notching or cross-talk, DC bus over-voltage trips, inverter overcurrent and over-voltage, and poor total power factor. Since all drives demand nonlinear current and voltage, drives demand currents rich in harmonics.
* KLR line reactors provide additional circuit inductance which slows rapid changes in current that are the heart of the problems listed above.
1. Voltage line notching, or commutation notching, is caused by SCR phase-controlled rectifiers. KLR line reactors provide a voltage-dividing impedance which reduces the depth and rounds the edges of the notches, thereby eliminating drive cross-talk, interference, and equipment damage. Transient voltages on the AC power lines can cause inrush currents to an AC-PWM drive, resulting in an over-voltage condition of the DC bus.
2. These transient voltage conditions are often caused by utility capacitor switching and will cause VFDs to shut down without warning. The addition of a KLR line reactor will Figure 1 - Voltage transient caused by switched capacitor.
