Harmonics in electrical power systems: Effects of new technologies
The purpose of this paper is to bring engineers up to date and give them new tools for solving harmonic problems. Variable Frequency Drive (VFD) technologies previously used only in high power applications, such as Pulse Width Modulation (PWM) Drives, Active Front Ends, and 18-pulse rectifiers have moved to lower voltage and power levels. They are now widely used in industrial and commercial power systems. The techniques used in conventional harmonic analysis for the 6-pulse SCR drive no longer apply in many cases. New harmonic limitation devices, such as broadband and active filters are replacing the conventional notch filter.
