A new contribution into the improvement of power factor correction

Abstract

This paper presents an improved new method for power factor correction and harmonic current reduction using IGBTs and a passive filter which is suitable to compensate rapidly changing loads and reactive power. Furthermore, a single-phase control concept is discussed for simplicity. The results can be implemented in three-phase systems without any problems. It also presents a brief discussion of the main problems in the distribution power systems. The increased use of nonlinear devices cause voltage distortion in the network. This leads to malfunctions of the electric facilities and to costly interruptions of production. The filter circuit parameters are analysed and described. This filter configuration provides an alternative approach to the existing one. According to the test results, the proposed approach can achieve a complete elimination of harmonics.
