This paper presents the final results of the activities carried out by the authors to estimate the reliability and availability performances of an innovative modular power conversion architecture, developed within the UNIFLEX-PM (Universal and Flexible Power Management) EU project. The performed study addresses also the analysis of the effects on system stochastic performances deriving from basic components wear out phenomena, and the ones deriving from the adoption of different redundancy strategies and maintenance policies. The UNIFLEX-PM architecture represents an innovative solution for power management in the distribution networks, thus the reliability and availability studies have been focused on obtaining basic figures useful to define the effectiveness of the proposed solution through comparison with a power converter architecture already used for building commercial products and assumed as the reference case. The results show that with a suitable technological choice for some critical basic components (such as the DC link capacitors), the UNIFLEX-PM stochastic performances are fully comparable with the ones provided by the commercial solution.

Abstract

This paper presents the final results of the activities carried out by the authors to estimate the reliability and availability performances of an innovative modular power conversion architecture, developed within the UNIFLEX-PM (Universal and Flexible Power Management) EU project. The performed study addresses also the analysis of the effects on system stochastic performances deriving from basic components wear out phenomena, and the ones deriving from the adoption of different redundancy strategies and maintenance policies. The UNIFLEX-PM architecture represents an innovative solution for power management in the distribution networks, thus the reliability and availability studies have been focused on obtaining basic figures useful to define the effectiveness of the proposed solution through comparison with a power converter architecture already used for building commercial products and assumed as the reference case. The results show that with a suitable technological choice for some critical basic components (such as the DC link capacitors), the UNIFLEX-PM stochastic performances are fully comparable with the ones provided by the commercial solution.
