INTERLOCK SWITCHING CIRCUIT FOR PROTECTING AN ELECTRICAL ON-BOARD POWER SUPPLY

摘要

The invention concerns an interlock switching circuit for protecting an electrical on-board power supply for an electrically drivable vehicle. The interlock switching circuit comprises a conductor loop, a first current source, a first current mirror and a second current mirror. The first current source is designed to drive a current flowing out of the input of the first current mirror into the input of the second current mirror. The conductor loop is connected between an output of the first current mirror and the output of the second current mirror.
