DC VOLTAGE CONVERTER ARRANGEMENT, FUEL CELL VEHICLE AND METHOD FOR OPERATING A DC VOLTAGE CONVERTER ARRANGEMENT

A DC voltage converter arrangement includes a plurality of full switch bridges and transformers and is for a galvanically separate, at least indirect electrical coupling of a fuel cell unit to a traction network including a high-voltage battery. The plurality of full switch bridges and transformers transform a DC input voltage to an alternating voltage, transform the alternating voltage to a transformed alternating voltage, and transform the transformed alternating voltage to a DC output voltage. At least one of the full switch bridges is included in a resonance circuit including an inductance and a capacitor.
