“…These devices produce a lot of harmonics generated by cutting the input electrical sine-wave. The harmonic distortion in the input current has harmful outcomes on the power electrical networks and will not comply with international standards such as IEC 61000-3-2 (class C equipments) [1][2][3][4][5]. Harmonic reduction of phase-cutting dimmers has attracted considerable attentions [6][7][8][9][10].…”

In this study and for the first time, a novel harmonic remover circuit is presented that removes the entire current harmonic distortion generated by the phase-cutting devices, which have ohmic input impedance (ohmic phase-cutting devices) such as lighting dimmers. The presented circuit has been designed and an experimental prototype has been built in the laboratory. It has a very exact operation to remove the total harmonic distortion (THD). It really removes the entire harmonic and the THD% of the compensated device is equal to the THD% of the same device without any phase cutting, so if the THD% of the system without any phase cutting is zero then the THD% of the compensated device will also be zero. The real measurement and experimental results are presented to validate the theoretically results and make a comparison between the advantages of this work and other related works.
