Firstly, the distribution reliability of power 等领域[1-3]，承担着电能变换、新能源发电等重要作 electronics devices is shown in the paper, and the failure 用。随着电力电子电路日趋复杂，功率等级不断提 mechanism and failure feature of active power switches 高，特别是应用在某些重要领域如航空、航天时， MOSFET, IGBT are analyzed. The FFE of the active power switches are classified into two categories: one is the direct 对电力电子电路可靠性的要求更高。电力电子主功 extraction
