The report presents the results of test and evaluation of commercially available AC power filters, and examines the filter pulse response in light of its measured and calculated pass band characteristics. The power line source impedances encountered in insertion loss measurements have been measured and modeled by an equivalent circuit. A coaxially shielded bench set-up for convenient insertion loss measurement of power filters utilizing the NCEL current injection probe method was devised. The insertion loss and pulse response have been determined theoretically and compared with experimental measurements for some unique filters designed to prevent inductor saturation. The effects of resistive damping to improve a power filters pulse response have been investigated, and recommended damping techniques presented. The effect of varying the load power factor upon the resistive damped filter performance has been determined. Author
