Algorithm Research of the Inverse Matrix in the Solution
of the Inverter Harmonic Elimination Model

Abstract

Abstract: Various matrix inversing methods and their algorithm stability are analysed．It is found that the convergence of mathematic solution of selective harmonic elimination equation results from morbid-condition of the selective harmonic elimination matrix．The inversing method with Gauss-Jordan elementary transformation based on the compact memory is presented and calculation steps are described in detail． The results show that the algorithm has many meritssuch as little memory occupyinglittle calculation easy suited to parallel calculation and so on．Thereforeit is an effective method to get inverse matrix．

Key words: selective harmonic elimination, inverter, solution of inverse matrix
