In industries DC motor drives are very essential due to their high performance applications such\nas its reliability, ease of control, low cost and simplicity. And speed control of these motors is very\neasy due to power electronic AC-DC converters. These power electronic converters are with\nprominent low power factor and higher Total Harmonic Distortion (THD). These converters operate\nonly for short time resulting non-sinusoidal waveform. This problem of harmonic distortion\ncan be mitigated by reshaping the non-sinusoidal waveform to pure sine wave. Different wave\nshaping techniques have been developed by using different filters among which one is tuned passive\nfilter. This paper proposed power factor improvement and harmonic mitigation of AC-DC\nconverters based on separately excited DC motor using tuned passive filter. In this context experimental\nmodel is designed and results are analyzed by power quality analyzer.
