Natural Resources Canada's Office of Energy Efficiency has produced a Variable Frequency Drive (VFD) video demonstrating how variable frequency drives generally work and their application in industry.

VARIABLE FREQUENCY DRIVES Energy Efficiency Reference Guide

Application Guide for AC Adjustable Speed Drive Systems by the National Electrical Manufacturers Association (NEMA) is a 73-page publication that provides a wealth of information on selecting, installing and using VFDs.

DrivesMag, an online trade magazine serving the variable speed motor drive industry, is an excellent reference on VFDs and includes a library of articles on drives. Most North American manufacturers, their products and specifications are listed - including power quality and harmonic mitigation filter manufacturers. This index also has many other useful resources for AC drives and includes examples of VFD applications.

Ontario Hydro's Adjustable Speed Drive Reference Guide is a 103-page guide containing a wealth of information on adjustable speed drives (ASDs), including principles of operation, a comparison of ASDs, advantages, application considerations, economics, harmonic distortion, and a list of ASD suppliers in Ontario.

The Canadian Energy Efficiency Centre lists VFD distributors and manufacturers. Click on the link for “New product information: Variable Speed Drives.”
