Power conversion plays an important role in our world nowadays. Conversions from AC to DC and to AC back are done in order to control AC motor speed and other electrical equipment. The voltage and current are controlled in this conversion but there will be some power losses due to switching in rectifier and inverter. Among the most desirable features in power converter are simple and compact power circuit, generation of load voltage with arbitrary amplitude frequency, regeneration capability, and operation with unity power factor for any load. These ideal characteristics can be fulfilled by matrix converter (MC) which is become increasingly attractive for the AC drive applications. It has the potential to replace the conventionally converter. There are some limitations for this matrix converter and first of all, it has a maximum input-output voltage transfer ratio limited to approximately 87% for sinusoidal input and output waveform. It also requires more semiconductor devices than conventional AC-AC converter since no discrete bidirectional IGBT switches exist. This paper studies about three phase to three phase matrix converter in terms of performance and its technology issues. The simulation are done in MATLAB/Simulink to show that matrix converter is just one of the possible direct AC-AC converter topologies by analyzing the output of phase voltage, line voltage and current along with the harmonic that occurs. Some improvement for this matix converter also has been stated in this paper in order to achieve desired output.
