Abstract :
This paper analyzes the power cycling capability of IGBT modules in a conventional matrix converter used as a motor drive. The analysis is made under various condition for this topology, including low speed operation capability, high speed thermal and power cycle capability and etc. It was found that the power cycling mean time to failure (MTTF) of IGBT in a matrix converter is low when the input and output frequency is close to each other or when the output frequency of the converter is low. As a result, the chip size of the conventional matrix converter may be larger than the other candidates. In the end of the paper, some guidance of designing a matrix converter for long term reliabilities is also discussed.
