Reasons for Matrix Filters

Why are Matrix Filters Necessary?

They Increase Reliability
Matrix Filters reduce the burden on electrical equipment by reducing TRUE RMS (trms) current, peak current and harmonic frequency distortion. The series impedance included in the Matrix filter also absorbs transient over voltages just like a line reactor, to prevent over voltage trips and rectifier damage. Inc raised system reliability means higher productivity.

They Increase Equipment Life
Matrix Filters reduce the trms current that flows through equipment feeding non-linear loads. This reduces the amount of heat generated by upstream equipment (such as transformers, disconnects, fuses, circuit breakers and conductors), thus extending their life expectancy.
They Reduce System Harmonics
Matrix Filters can reduce adjustable speed drive system harmonics to negligible levels.

They Reduce Current Waveform Distortion
Matrix Filters improve the input current waveforms of non-linear loads to nearly sinusoidal. This results in lower peak current and trms current demands while achieving a cleaner power supply.

They Save Energy!
By nearly eliminating the wasted energy associated with harmonics, Matrix Filters reduce the trms KVA demanded from a power source.
They Meet IEEE-519
Matrix Filters allow you to meet the voltage and current distortion limits of IEEE-519, EN61000, AS2279 and G5/4.
