Impacts on Power Factor of AC Voltage Controllers Under
Non-Sinusoidal Conditions Keywords: AC Voltage Controllers, Bidirectional, Harmonics, Power Factor under Nonsinusoidal Conditions. Mehran University Research Journal of Engineering & Technology Volume 31 , Issue 2 Mukhtiar Ahmed Mahar,Abdul Sattar Larik,Syed Asif Ali Shah Abstract AC-AC conversion is obtained with the help of Cyclo-converters, DC Link converters and AC Voltage Controllers. AC voltage controllers are also referred to as voltage regulators. Main issue concerned to these converters is that they generate harmonics due to periodic variable structure system. The generated harmonics create disturbances and degrade the performance of converter. The power factor of supply side is affected due to these harmonics. This paper focuses on source side power factor of ac voltage controllers under nonsinusoidal conditions. In order to observe the power factor, measurement tool of power factor and simulation model of ac voltage controller is also developed in MATLAB software. |
