Reverse polarity protection device for electrical protection of a DC voltage converter, method for providing electrical protection of a DC voltage converter and motor vehicle with a reverse polarity protection device

摘要

The invention relates to a reverse polarity protection device (10) for the electrical protection of a DC voltage converter (50), which is used, for example, in a vehicle electrical system. The reverse polarity protection device (10) comprises a first input connection (12) and a first output connection (16) as well as a second input connection (14) and a second output connection (18). The reverse polarity protection device (10) further comprises an electronic circuit breaker (20) which is arranged between the first input connection (12) and the first output connection (16). A control connection (22) of the electronic circuit breaker (20) is coupled to the second input connection (14) and / or to the second output connection (18).
