Patent ID: 11349472

Abstract:
A method for reducing a thermal load on a switching element of an electronic fuse when switching on a load, wherein (a) a switching element is activated, (b) the switching element is deactivated and (c) the switching element is re-activated after reaching a set value of a switch-off duration, where steps (b) and (c) are repeated until an output voltage reaches a value that falls below a specified difference with respect to an input voltage of an electronic fuse or an output current reaches a specified duration current, where set values of a switch-on duration and/or switch-off current and the switch-off duration are maintained until new set values have been determined based on the output voltage, output current, and/or temperature, a pulse duty factor between the switch-on duration and the switch-off duration is adapted, and the specified maximum allowable temperature increase of the switching element is further observed.
