Investigating the EMC Performance of a Matrix Converter and Measures to Improve It

Electromagnetic interference caused by nonlinear loads can significantly affect electronic equipment in a system, especially those that operate on low amplitude control signals. Matrix converters is an example of such nonlinear loads. This paper investigates through measurements, the EMC behavior, radiated and conducted emissions by a matrix converter, compares this performance to conventional converters, and defines mitigation measures employed to improve the EMC performance and reduce any risk of interference. These mitigation measures follows a risk based approach and can thus be designed according to the given electromagnetic environment in question, on board ships.
