Abstract :
Harmonic current is one of the major power quality problems due to non linear loads. In this paper the harmonic current in induction furnace load is compensated using active power filter. The inverters and rectifier switching creates harmonics in input side. It is then compensated by using active power filter with p-q theory and PI controller. The simulation result are obtained with FFT analysis and shows the minimisation of current harmonic.
