An overvoltage protection circuit for a first subsystem of a multivoltage vehicle electrical system, in which the first subsystem having a first vehicle electrical system voltage, a second subsystem having a second vehicle electrical system voltage, and an electric machine for supplying the second subsystem. The first system voltage is less than the second system voltage. The overvoltage protection circuit includes a first ground connection for connecting a shared ground potential of the first subsystem, the second subsystem, and the electric machine, an additional second ground connection for connecting a reference ground potential, and a control connection for controlling the electric machine. The overvoltage protection circuit checks whether a ground differential voltage between the first and second ground connections reaches a threshold value, and for reducing the second vehicle electrical system voltage when the ground differential voltage between the first and second ground connections reaches the threshold value.
