| Abstract: | reliability analysis method for power electronic circuits based on the weighted network model was presented in this paper, and a Flyback converter base on UC3842 was illustrated as an example. At first, the weighted network model of the Flyback converter was built base on the component failure rate, then the complex network characteristic could be confirmed by calculating the model parameters. Finally, the key components in the circuit could be defined by quantifying the influence of each component under different failure rate, and the method which is useful to improve the reliability of power electronic circuit could be proposed. |
