dc.description.abstractThis thesis describes the use of an array of power semiconductors (series transistor array) and a buck-boost transformer in the design and implementation of a single phase AC voltage regulator. The power semiconductor array was used to act as variable impedance across the bridge points of a rectifier. The input point of the bridge rectifier was also connected directly to the primary winding of the buck-boost transformer. A closed loop circuit was designed using an RMS/DC converter chip, with complete electrical isolation between the low voltage control circuits and the power circuits. The major advantages of this technique are: fast response to RMS voltage fluctuation; waveform fidelity; light weight; and reduced size compared to that of a servo-driven AC voltage regulator such as the PS10 Smart Power Station, which was used in this project as a benchmark for the AC voltage regulator using the power semiconductor array. The device used for testing the performances of both AC voltage regulators was the NoiseKen VDS-2002 Voltage Dip and Swell Simulator. This simulator was used to perform voltage dip, swell, interruption, and variation tests in a manner fully compliant with IEC 61000 – 4 – 11.
