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.
