A control circuit () is configured and intended for use in an electric vehicle (). The control circuit () comprises a first circuit portion (), a first power supply line (), a first controllable switch (), a second circuit portion (), a second power supply line (), a second controllable switch () and a switch control unit (). The first circuit portion () comprises at least one electrolytic capacitor (). The first power supply line () is configured to supply the first circuit portion () with electrical power. The first controllable switch () is arranged in the first power supply line (), wherein the first switch () interrupts the first power supply line () in an open state in order to prevent the at least one electrolytic capacitor () from being supplied with power. The second power supply line () is configured to supply the second circuit portion () with electrical power. The second controllable switch () is arranged in the second power supply line (), wherein the second switch () in an open state interrupts the second power supply line (). The switch control unit () is configured and intended to control the switching states of the first switch () and the second switch (), wherein the first switch () and the second switch () are closed in a first control state, and wherein in a second control state the first switch () is open and the second switch () is closed, wherein the switch control unit () is further configured and intended to determine the control state on the basis of functional requirements of the electric vehicle ().
