This article details a new transfer function approach in passive harmonic filter design for industrial and commercial power system applications. Filter placement along with six common filter configurations are presented. Harmonic impedance, voltage division and current division transfer functions are derived and used in a practical filter design procedure that incorporates IEEE-519 distortion limits directly into the design and component specification process. A simple four-step filter design procedure is outlined and used in a variable speed motor drive pumping plant application
