Active Fuse

In this work, we propose an active fuse which is a novel power device to prevent serious hazards in power electronics in the case of a fault. Using this active fuse, power devices or parts of power electronic circuits which are in an undefined, uncontrollable condition can be disconnected reliable and irreversible from the power supply. Critical safety consequences of faults like overheating or fire will be avoided. The focus of this work was to develop a monolithic integrated crowbar circuit including a fusible element $the active fuse - with an application range from 1A to 5A and 48V at an operating temperature of 175degC
