Electric circuit for discharging a capacitor, electric system and motor vehicle comprising such an electric discharge circuit

Abstract

The electrical discharge circuit (106) includes: —two interface terminals (BA, BB), to which the capacitor (C) is intended to be connected and across which a capacitor voltage (uC) is intended to be present; —a current-consuming electrical circuit (108) connected between the two interface terminals (BA, BB) and designed to consume a discharge current (i) from the capacitor (C); and—an electrical control circuit (110) for controlling the current-consuming electrical circuit (108), the electrical control circuit (110) being connected between the two interface terminals (BA, BB) so as to receive the capacitor voltage (uC). The electrical control circuit (110) is designed: —to deactivate the current-consuming electrical circuit (108) when the capacitor voltage (uC) is above a predefined threshold; and—to activate the current-consuming electrical circuit (108) when the capacitor voltage (uC) across the two interface terminals (BA, BB) is below the predefined threshold. The electrical control circuit (110) is furthermore designed to be supplied with electrical power exclusively via the two interface terminals (BA, BB).
