Taking advantage of the harmonics at the load side using passive filters

This paper presents a novel idea to show the ability to benefit of the harmonic currents which are produced on the load side of the power grid. The proposed circuit contributes in reduction of the Total Harmonic Distortion (THD) percentage through adding a High Pass Filter (HPF) in order to draw harmonic currents (in 150 Hz and multiple frequencies) and convert them to Direct Current (DC) (zero frequency) and then reconvert it to Alternating Current (AC) current with the fundamental frequency in order to feed different loads. The circuit has been designed and simulated in the MATLAB, Simulink program. The results have been assessed and compared in two cases: firstly, the system before adding the new circuit. Secondly, the system after adding the new circuit.
