MAGNETICALLY CONTROLLED REACTOR FOR HARMONIC ELIMINATION

Abstract

Power electronics has revolutionized the electrical industry but it comes with certain drawbacks. Harmonic is one of the issues with the power electronic system which needs to be addressed. Currently, a passive filter is being used to eliminate these problems. N-numbers of tuned filters are required to eliminate various harmonics. Effective use of filter can be done by the use of special purpose of reactor known as Magnetically Controlled Reactor (MCR). This paper presents a new filtering scheme with the use of MCR which works on the principle of DC biasing. Proper controlled excitation is given to the DC bias to have control on the reactance value. This paper also explains more about the control algorithm, the filter performance analysis through simulation results.
