| Abstract |
This paper proposes reliability block diagrams for various photovoltaic (PV) system topologies andevaluates their reliability functions and mean time to failure (MTTF). The paper presents sensitivityanalysis of the system MTTF with respect to individual failure rates of power electronic converters.The proposed approach can be used to determine reliability specifications of required converters interms of desired MTTFs based on a desired PV system MTTF. This creates a reliability feedback loopto refine the PV system topology leading to a 'design for reliability' approach. Results and reliabilitymodels proposed in this paper can be used for further comparing the reliability of different powerelectronic topologies in PV applications, and can extend to a wide range of energy systems utilizingpower electronic converters. |
