REVIEW OF MATRIX CONVERTER FOR FREQUENCY CHANGING APPLICATIONS

Abstract

It is possible to achieve bi-directional power flow with a Matrix Converter and by controlling the switching devices appropriately; both output voltage and input current can be sinusoidal. This is   only true if there are no power fluctuations in the load which would be fed to the input supply with a consequent distortion of the line currents. Switches with the capability of current flow both directions (to and from the load) must be used in order to permit the bi-directional power flow. This is an important issue which has been taken into consideration when looking at the characteristics of any application. In order to optimize the design of the Matrix Converter system, which is going to operate as a power supply for aircraft applications, a detailed analysis using both Saber and Matlab/Simulink software packages were used to select the best topology of Matrix Converter system that could satisfy the specifications. When Saber was used, the Matrix Converter modulation and control were implemented by using the MAST language, which discretised the modulation strategies applied.
