SENSITIVITY ANALYSIS OF SPACE VECTOR MODULATED MATRIX CONVERTER

Park transformation technique is applied to the space vector modulated matrix converter with the input filter. The equivalent 4-port network of the switch matrix is obtained. Based on this 4-port network, the matrix converter is turned into the equivalent linear time-invariant circuit without switch. Thus the analysis of the matrix converter becomes as easy as that of the conventional circuit. The accompanying network model. which is used to analyze the sensitivities, is established. The formulae to calculate voltage gain sensitivities with respect to the filter parameters and control parameters of the matrix converter are derived theoretically. The calculation steps to analyze sensitivities by means of the accompanying network method are given in detail. The validity and applicability of the algorithm are verified through the MATLAB simulation.
