Output voltage regulation in matrix converter fed power electronic transformer for power systems application in electric ship

Abstract

The system described in this paper uses three matrix converters and a high frequency transformer to achieve isolation and voltage transformation from primary to secondary side. Two matrix converters produce high frequency voltage across a transformer, with open ended primary. A third matrix converter converts the high frequency chopped voltage to line frequency. The non-idealities such as leakage inductance of the transformer have a significant effect on the converter performance. This paper studies the effect of leakage inductance on the regulation of the output voltage of the converter. The simulation study has been carried out in SIMULINK and the results have been presented.
