Best-in-class SineWave Filter for cleaning PWM output from VFD.
Output of all VFD having PWM waveform with high frequency and voltage peak. It will damage Motor, Cable and connected Load equipment. Prima Transformers Pvt Ltd designed Sine Wave Filters transform the output of Variable Frequency Drives (VFDs) to a near perfect sinusoidal waveform for the best level of motor protection. Prima’s unique, design offers high performance with smaller size and better efficiency than traditional LC Filter.
The Sine Wave Filter also offers incredible reliability and durability. It is more efficient and tolerates higher ambient temperatures, making it ideal for a variety of applications from steel mills to oil fields. Its modular design and smaller footprint make it easier to integrate and install.
Increase motor life: Reduce motor heating through reduction of high frequencies associated with VFD output and also reduce motor insulation stress through reduction of motor peak voltages.
Reduce motor audible noise:Reduce audible noise through reducing high frequencies associated with VFD output. Reduce radiated emissions: Reduce emissions through reducing high frequencies associated with VFD output.
Protect your motor cable: The reduction of high frequencies associated with VFD output eliminates the need for special motor cables.

Adaptive Passive Technology for superior harmonic mitigation at varying loads
Simply put, our Harmonics Filter is the most advanced passive filter on the market today. Most traditional filters work fine at 100% power load, but severely underperform at lower loads. Our Harmonics Filter is different, because we know almost no one runs at full load all the time. Its patented Adaptive Passive Technology virtually eliminates harmonic distortion by adapting to varying power loads. It delivers better THID performance, increases energy efficiency, and allows you to meet IEEE-519 requirements. Its unique design generates less heat, and is easy to install and maintain. Plus it is generator compatible. With Prima’s Harmonic Filters, power quality, energy efficiency and reduced downtime are easy to achieve.
The best-in-class Prima’s Harmonic Filters can be specified for use on the input of your VFD or other 6-pulse rectifier power supply to enable your system to meet the IEEE-519 requirements for harmonic distortion, regardless of power load.
Features our patented Adaptive Passive Technology for superior harmonic mitigation and better THID performance over a wider load range.
Prima’s performance guarantee provides peace of mind that the Matrix AP will meet or exceed performance expectations - every time.
Extends service life of electrical equipment, especially transformers and motors, due to the virtual elimination of CEMF and the skin effect.
Alleviates system downtime by preventing blown fuses and tripped circuit breakers.
Harmonic Filters can help ensure that your system meets the IEEE-519 requirements for harmonic current.
