Matrix Converter Output Voltage Control with Overmodulation

Popis výsledku v původním jazyce

The matrix converter is a very popular topic today. Many papers about matrix converter deal with modulation strategies and control algorithms. In this paper, special attention is paid to the indirect space vector modulation, which is based on the virtualdc link concept. The entire converter is interpreted as a series connection of two matrix converters (rectifying and inverting virtual matrix converter). Thanks to this insight, it is possible to compose the modu- lation strategy for the entire matrix converter from the inverter and rectier part modulations. The main goal is to achieve the maximal possible output voltage by overmodulation employ- ment. The overmodulation method based on the indirect vector modulation is presented. By means of the square wave modulation the voltage transfer ratio can be increased from 0.866 up to 0.955. Moreover, together with control of the current modulation index, a linear and continuous adjustment of the output voltage can be achieved.
