Analysis of different schemes of matrix converter with maximum voltage conversion ratio

The aim of this paper to investigate the different schemes of matrix converter under R-L load condition and also to obtain maximum voltage transfer ratio of matrix converter. Matrix converter is a new type of direct AC/AC converter, which converts input line voltage into variable voltage with unrestricted output frequency without using intermediate circuit, DC-link circuit, pure sine-in and pure sine-out is the unique feature of the matrix converter. But maximum voltage transfer ratio of matrix converter is limited to 50%. This is the major disadvantage of matrix converter. This limitation can be overcome by eliminating third harmonics by injecting third harmonic voltage in the input voltage; the maximum voltage transfer ratio 100% is achieved. This paper also analyzes the basic operating principle and simulation modeling of different schemes of matrix converter such as 1. Two phase to single-phase matrix converter. 2. Three phase to single-phase matrix converter. 3.Three phase to three phase matrix converter using PSPICE software.
