The invention relates to a design for increasing the switching speed of a power electronic switching device and application, and belongs to the technical field of design for increasing the switching speed of the power electronic switching device. The invention aims at a switching speed bottleneck of a power electronic power switch (unit piece/module) chip. Conclusions of some common knowledge points are concluded and applied to propose a design scheme. A part of circuit structure is added to the chip concisely, so that the chip works in a set quasi-saturated voltage stabilizing state in a conducting state (later period), the power switch component can obtain breakthrough of the switching speed of the component and improvement of reliability performance, and the application of the power switch component can be further expanded. 本发明为一种提高电力电子开关器件开关速度的设计和应用本发明所属技术领域涉及一种提高电力电子功率开关器件开关速度的设计。本发明针对电力电子功率开关(单元件/模块)芯片的开关速度瓶颈，归纳应用了一些常识性知识点的结论以提出设计方案：将芯片简洁地增加部分电路结构，使其在处于导通状态(后期)工作在设定的拟饱和稳压状态，让功率开关元器件能获得元器件开关速度的突破及可靠性性能的提
