碩士 === 國立高雄應用科技大學 === 電機工程系 === 98 === Silicon-controlled current-source rectifiers have been widely applied in industries. However, they cause problems of harmonic current and voltage notch, resulting in serious degradation of power quality of the utility. In this paper, the voltage notch is discussed, and several solutions to improve power quality of the silicon-controlled current-source rectifier are analyzed. In this thesis, a hybrid solution, comprising both hybrid and passive power filters, is proposed to mitigate the problems of poor power factor, harmonic current, voltage distortion and voltage notch caused by the silicon-controlled current-source rectifier. Finally, computer simulation is carried out to evaluate the performance of these passive and hybrid solutions to improve the power quality problems caused by the silicon-controlled current-source rectifier.
