All modern AC drives produce sufficient amounts of Radio Frequency Interference (RFI) to potentially affect the operation of equipment susceptible to this type of noise. The likelihood of encountering problems with RFI is increased in older buildings, where grounding is either inadequate or lacking altogether. IGBT’s as a Noise Source: Modern AC drives use power devices known as Insulated Gate Bipolar Transistors, or IGBTs. These devices make it possible to minimize annoying audible noise, using switching frequencies beyond the human audible range. Unfortunately, AC drives using IGBTs present a high potential for generating Radio Frequency Interference, or RFI. The fast switching that characterizes these devices generates sharp-edged waveforms with high frequency components. The most likely complaint is interference with AM band radios in the 500-1600 kHz range. Noise-sensitive devices sharing the same power bus, including computer and medical equipment, could also be disrupted by interference.

 

 

 

 

 

 

HOW TO REDUCE THE EFFECT OF RFI AND EMI:

Proper grounding, including correct ground conductor sizing Proper routing of field wiring Controller design and layout Use RFI filters Use drive isolation transformers Higher installation “standards of care”

 

 

 

GROUNDING

One contractor experienced multiple elevator system problems that were ultimately determined to result from the building’s lack of good grounding. A solid earth ground was provided and many electrical noise problems were eliminated. Still, the elevator controller itself was being affected by undetermined sources of noise until proper grounding principles were applied
