In this paper, the fractional characteristics of capacitor and inductor are considered, and the single tuned passive harmonic filter is modeled and analyzed based on the fractional calculus. The fractional-order mathematical model of the single tuned passive harmonic filter is given. The difference between the integer model and the fractional model is revealed. In the fractional model the reson…
Filter detuning strongly affects the filter's size and operating performance. Partial resonance is recommended to raise the filtering efficiency of a single-tuned filter at the worst point in the detuning range. This paper presents a new way to obtain the optimal tuning frequency of a single-tuned harmonic filter in order to control harmonic currents to the allowable value with a minimum filter…
