Abstract：Power electronic devices and equipment work under the pulse voltage with high repetition frequency and steep rising and falling edges in the long term. The insulation is more prone to occur early insulation failure, which seriously threatens the reliability and stability of power systems. Therefore, it is of great significance to clarify the mechanism of insulation degradation and breakdown under the pulse voltage, ensuring the safe and stable operation of power systems. In this paper, several common power electronic devices and its operation condition are introduced, and the important role of charge behaviors in insulation degradation is revealed through the discussion of the mechanism of insulation breakdown and flashover. Moreover, the effect of pulse voltage parameters on charge characteristics is introduced. Besides, the shortcomings of the current research are summarized and discussed. In future research, the charge test technology under pulse voltage needs to be improved, and the dynamic characteristics of the charge at the pulse edges should be deeply explored to clarify the mechanism of insulation degradation. The summery of these research results provides reference and theoretical guidance for the optimal design of electronic devices and equipment insulation materials and system under the pulse voltage.
