摘要
In the present era when PWM AC/AC voltage controllers are widely used in UPS and high power flexible AC transmission systems power factor can be improved and more number of harmonics can be reduced using the pulse width modulation techniques of a voltage waveform. It discloses various PWM techniques on the AC/AC voltage controller without DC link and two configurations of PWM technique for harmonics reduction and improvement of power factor and output voltage. In the present innovation fast switching device, PWM techniques can be applied to AC/AC voltage controllers for producing variable output voltage with a better input Power Factor which may well illustrated by theoretical results validated through simulation studies using PSIM software package.
