Reduction of Harmonics to Improve Performance of Permanent Magnet Brushless DC Motor Drive Using Cuk Converter

The Presence of harmonics the input supply of permanent magnet Brushless DC Motor cause decrement of efficiency due to the power losses in higher frequency content waveform. This will also cause low power factor because of higher the harmonics which  causes higher consumption of reactive power and so the overall power factor will decrease. Thus it is necessary to increase the input wave form by reducing the present harmonics. This paper deals with the cuk converter to decrease the harmonics contend in input of permanent magnet Brushless DC Motor. The Result is showing in this paper is comparatively study of wave form with and without the cuk converter based permanent magnet Brushless DC Motor.
