Abstract |
Redundancy strategies have been used to ensure continuity of service facing catastrophic failure events in power converters. However, additional parts are needed, resulting in increased cost, size and weight. The increasing demand of high power density and low-cost systems, motivates more reliable converters with few additional parts. This work, address the scientific question on which modular dc-dc converter shall be selected to achieve a required residual power with minimum redundancy level. The Smart Transformer is used as a case study for a probability analysis of power derating, under successive failure events.It is shown that the Multiple-Active Bridge based converters have higher probability for more residualpower in multiple failure scenarios, and ensure high reliability in long operating time with minimumredundancy level. |
