Self-switching circuit based on IGBT suited for monolithic integration

A new self-controlled and self-protected integrated power switch dedicated to self-switching mode power converters is presented. To achieve this function, an original topology based on an IGBT is proposed and its operation is analysed by 2D physical simulation. The topology validates the functionality, the switching phases are instantaneous and the switch is compliant with technical specifications. These results motivate the realisation of this device, offering promising potential for a wide range of applications.
