Abstract

The power loss analysis of matrix converter based on RB-IGBT is discussed in this paper. The on-state performance and switching process of RB-IGBT are tested; the on-state curve is obtained by the mathematical fit of the experimental data; On the basis, a method of power loss calculation for matrix converter under the input line-to-line voltage control strategy and four-step commutation strategy is investigated; Finally, the simulation result obtained by MATLAB/Simulink verifies the correctness and validity of the proposed method.
