A circuit arrangement for providing electrical power for at least one DC load from at least one alternating current source having a primary DC intermediate voltage circuit. The primary DC intermediate voltage circuit is supplied with electrical power of the alternating current source via two rectifiers connected in series such that a centre point tap is provided, means for limiting the DC output voltage of the associated rectifier are provided between the centre point tap of the primary DC intermediate voltage circuit and at least one DC potential of the primary DC intermediate voltage circuit, which can limit the DC output voltage of at least one of the rectifiers connected in series in the event of a fault state in the DC load, in the secondary DC intermediate voltage circuit and/or in at least one of the DC/DC converters.
