A novel over modulation methodology for dual bridge matrix converter (MC) is first put forward in this paper. Based on amplitude control of the rectifier side and inverter side, an over modulation methodology is presented. First the rectifier side is separated into six intervals to get the maximum DC voltage, and then a novel over modulation strategy is invented for the inverter side, which can manage...
A lot of research has been made on space vector modulation (SVM) strategy of matrix converter, but research on over modulation strategy of MC is almost blank. This paper analyzed conventional control theory of two-stage matrix converter, derived voltage transmission characteristic, then presented an over modulation method, which covered the entire over modulation range. The method was divided into...
A novel over modulation strategy for matrix converter (MC) is put forward on the basis of conventional AC/DC/AC MC control theory. First, fictitious AC/DC rectifier is over modulated to get the greatest dummy DC voltage, then a novel over modulation strategy was invented for the inverter side, which effectively enhanced voltage transfer ratio to 1.05 with good linearity. At last, the method was extensively...
