| Abstract: | The IGBT short circuiting protective circuit with optimum performance is designed and studied on the basis of the principle of collector emitter voltage desaturation detection and the limitation of IGBT short circuit safe operating area(SCSOA).The experimental results show that the short circuiting protective circuit is fast,safe,reliable and simple,and is of great application value. |
