SWITCH LOAD SHEDDING DEVICE FOR A DISCONNECT SWITCH

摘要

A switch load shedding device for a disconnect switch may be used in electric vehicles. The disconnect switch must perform a galvanic disconnect between the battery and the intermediate circuit. To this end, at least one semiconductor switch is used. The current to be switched off is conducted via the semiconductor switch for disconnecting the electric connection. The disconnect switch is previously or subsequently switched off under reduced voltage buildup.
