Novel Single Tuned Harmonic Filter not Affecting Fundamental Power Factor
TOTAL VIEWS: 4688
Abstract
In this paper, a novel single-tuned harmonic filter has been proposed, which can remove harmonics with the fundamental power factor unchanged. It can be applied to filter the harmonics made by a load whose fundamental power factor is 1 or capacitive. An example of such loads is a single-phase rectifier with a capacitor. The novel single-tuned harmonic filter has an LC branch whose resonance frequency is the same as the fundamental frequency, thus it does not pass the fundamental current and does not change the fundamental power factor. It has been discussed how to obtain the optimal filtering effect while considering the variation of parameters of the filter elements. Through simulations on the single-phase rectifier with a capacitor, it has been proved that the filter proposed in this paper does not affect the fundamental power factor and decreases the transmission loss by 0.53 times compared to the conventional one while providing the same filtering effect.
