Power factor is an indication of how effectively a load uses power. Utilities charge higher rates when power factor is low because of the extra burden imposed on the distribution system. Not only does the distribution system have to accomodate the real power being consumed, but it must also accomodate the reactive (non work producing) component flowing within the system. This white paper from Yaskawa America, Inc. takes a look at how variable frequency drives can be used to improve power factor.
