Abstract
Abstract: Currently, the prognostics and health management research of switch mode power supply (SMPS) are mostly based on the field data with specified stress profile, which can hardly be adapted to the application in other stress condition. A methodology research for health condition assessment of power supply based on simulation was proposed. The highly precise model was created for the injection of the quantitative degradation parameters of components. The database containing degradation characteristics of power supply was created by using design of experiment. The functions between stress factors and system outputs were confirmed based on least square method. Thus the health condition of the device will be estimated whatever the stress is. The demonstration of a flyback power supply validates the accuracy and effectiveness of the proposed methodology.
