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

The only passive harmonic filter designed for 3-phase VFD's operating on a 1-phase supply.

In remote locations such as farms, golf courses, oil and gas fields and residential areas standard 3-phase Variable Speed Drives are often used as Phase Converters to supply 3-phase motors when only 1-phase power is available. The Lineator™ 1Q3 is ideal for systems such as water and waste water, pump jacks, irrigation and many others.

The Lineator-1Q3™ has been designed to address this application by accepting 1-phase input and supplying a quasi 3-phase supply to the VFD. This will significantly lower both input harmonic current distortion (by up to 10x) and DC ripple current within the VFD. Reducing the ripple current allows for less derating of the VFD which, in many cases, will offset the cost of the Lineator-1Q3™.
