Abstract

This paper discusses the characteristics of a matrix converter determined using instantaneous space vector diagrams. Since 27 switching patterns are available for the matrix converter, 27 types of output voltages and input currents can be obtained. The instantaneous output voltages and input currents are plotted on an instantaneous output voltage diagram and an input current diagram, respectively. Then, the switching patterns of the matrix converter are visualized. From the instantaneous space vector diagrams, the output voltage ripple and input current ripple can be determined on the basis of the vector selected from among 27 instantaneous output voltage/input current vectors. In addition, the instantaneous space vector diagrams can be used to analyze the switching times.
In this study, six different of control methods for the matrix converter are evaluated by using instantaneous space vector diagrams and the total harmonic distortion of the output voltage and input current. The results lead to the conclusion that characteristics of the matrix converter can be effectively evaluated using the instantaneous space vector diagrams.
