Utilization of harmonics current in single phase system

Abstract

© 2016 IEEE. This paper presents a simple method to benefit of the harmonics current which is produced on the source side because of the nonlinear loads in single phase systems. The proposed circuit contributes in reduction of the total harmonic distortion (THD) and draw harmonics current via low pass filter (LPF) and create a useful power by rectifying the distorted current via full wave bridge rectifier (convert it to DC current) and reconvert it to AC sinusoidal current by using single phase inverter controlled by PWM circuit in order to feed different loads. The circuit has been designed and simulated in the MATLAB-Simulink program. It can be concluded from the results of the simulation, that the utilized current (I u ) can be created by rectifying harmonics current I h with simple design and low cost circuit without requiring any additional current drawn from the source and can feed RL-load.
