Mirus Harmonic Mitigation

Mirus Harmonic Mitigation - Quailty Passive filter for reduction of vcd and vfd


An easy to apply, passive filter capable of reducing Variable Speed Drive (VSD) / Variable Frequency Drive (VFD) harmonics by up to 10 times with none of the inherent problems of conventional filters.


Treats all major harmonics generated by Variable Speed Drives and other 3-phase rectifier loads (5th, 7th, 11th, 13th …)

Exceeds 18-pulse performance in a smaller footprint, at lower cost and without sacrificing energy efficiency Easily applied to input of a single VSD
No need to phase shift against other VSD’s
No need for costly harmonic studies
Will meet IEEE 519 standard for both current and voltage distortion
Input current demand distortion < 8% over entire operating range
Power factor 0.98 lagging to 0.95 leading over the normal operating range
Compatible with engine generators since capacitive reactance is < 15% of rated kVA even under light loads Will not resonate with other power system components Will not be overloaded by other line side harmonic sources |Suppresses overvoltages caused by capacitor switching and other fast changing loads Eliminates need for drive isolation transformers, AC line reactors and DC link chokes Removal of harmonics improves overall system power factor Saves energy by reducing upstream harmonic losses while operating at > 99% efficiency
Reduces DC bus ripple and increases ride-through capability of the load
