Abstract: In industrial applications there is a strong demand for power quality, energy efficient newlinepower converters with reduced number of switches. Matrix Converter (MC) has recently newlinereceived considerable interest, because it possesses the necessary features to fulfill these newlinecurrent trends. The most desirable features of MC in power converters are newlinea. Generation of output voltage with the desired amplitude and frequency newlineb. Sinusoidal input current newlinec. Sinusoidal output voltage newlined. Improved power factor newlinee. Regeneration Capability newlineBecause of these features, MCs replace Voltage Source Inverters (VSIs) in Induction newlineMotor (IM) drive applications. MC uses nine bi-directional controlled switches in a 3 x 3 newlinematrix form to produce variable output voltage with variable frequency. The main newlineadvantage of MC is that it does not have any dc link and energy storing elements which newlinereduce the performance of the converter. newlineThe output voltage of a VSC can assume only two discrete fixed potential values namely, positive newlineand negative DC bus values. In MCs the output voltages can assume any of the input voltages a, b or c and their values are not time variant and it reduces the switching harmonics. In the traditional VSC converters, the input current to the inverter stage contains 5th and 7th harmonics. newlineIn MCs if the switching frequency is kept higher than the input and output frequency, the input current drawn by the converter can be maintained sinusoidal. In VSC the power factor calculation needs the knowledge of the load displacement angle in order to control the power factor of the output whereas in MCs the knowledge of load displacement angle is not needed to control the power factor of the output. newline
