Abstract

PURPOSE: To realize fail safe by making the second semiconductor conductive by transmitting a trouble signal to the signal circuit connecting the first and the second semiconductors when the first semiconductor has been faulty, and flowing this short- circuit large current to weld the fuse, which is an overcurrent-opened element, and open the load safely.
CONSTITUTION: Overcurrent-opened element 24, for example, a fuse is inserted between the first semiconductor 23 and load 22, and the second semiconductor 26 is connected in parallel to load 22. When the first semiconductor 23 has been faulty, a trouble signal is transmitted to signal circuit 25 connecting the first semiconductor 23 and the second semiconductor 26. As a result, the second semiconductor 26 is made conductive to flow this short-circuit large current and weld the fuse which is an overcurrent-opened element, so that the load can be opened safely.
