Abstract
Electrical harmonics associated with switching power electronics have been observed to induce electromagnetic interference with equipment sharing the same electrical circuit, some research studies have documented cases of malfunction and even damage of particularly sensitive equipment resulting from this interference. The harmonic spectra of commonly used switching power electronics in a residential electrical system have been profiled before. This paper provides a phenomenological characterization of the voltage and current transfer function (in the frequency range 20Hz – 100kHz) from purported sources of electrical harmonics to the point at which a utility meter is typically installed (also the point of coupling to the service transformer). This work also evaluates the impact of shunt capacitance close to the point of coupling, resulting in a complex zero in the transfer function and the consequent impact on phase margins of the system.Proceedings Title
