Control device for reliability in case of malfunction of a voltage converter in motor vehicles

摘要

The control device (6) has a switching element (4), which is actuated by monitoring device (5) in such a manner that the switching element directly interconnects an input voltage (Vin) to output voltage (Vout) if the control device does not receive signal. The control device has potential transformer (2) that changes an input voltage upward or downward.
