SinglePhase AC–AC Converter Based on QuasiZSource Topology
ABSTRACT A Solid State AC/AC Converters converts on AC waveform such as main supply to another AC waveform. CONVERTERS : 1) Converters with DC link. 2) Cycloconverter. 3) Hybrid matrix Converter 4) matrix Converters. ACDCAC and matrix converters Provide variable output voltage and variable frequency. Applications: Voltage regulation. PWM ACAC Converters used to perform as AC choppers. Applications: For a better power quality, efficiency, low harmonic current in line, single stage conversion, simple topology. AC/AC Converters also perform Conditioning, Isolating, and Filtering of input power. The Direct PWM AC/AC Converters Derived from the DCDC topology. Where all unidirectional switches substituted by bidirectional switches. Converters are in two modes: AC & DC. In AC Converters implemented in both single phase and three phase system. Traditional Conventional System: To obtain the output voltage direct PWM AC/AC Converters are implemented ACthyristor controllers, which use phase angle of ac supply. Dis advantages : High THD(Total Harmonic Distortion),low input power factor. Advantages of proposed system : BuckBoost voltage, Reversing or maintain phase angle, low thd, high input power factor.
