  • Output capacitor array of a switched-mode power supply
    Patent number: 5493471
    Abstract: An output capacitor array of a switched-mode power supply includes at least one substrate having a layered stack of a positive-pole metal foil, an insulating foil, and a negative-pole metal foil. A plurality of electrically parallel connected individual capacitors are disposed on the at least one substrate. The capacitors have positive poles each being electrically conductively connected to the positive-pole metal foil, and negative poles each being electrically conductively connected to the negative-pole metal foil. A solid negative-pole metal rail is electrically conductively connected to the negative-pole metal foil, and a solid positive-pole metal rail is electrically conductively connected to the positive-pole metal foil and is insulated from the negative-pole metal rail, for carrying direct current in an input and/or output range of the output capacitor array.
