  • Relay arrangement with improved heat dissipation and converter device having a relay arrangement of this kind
    Patent number: 11570884
    Abstract: A relay arrangement includes at least two series-connected relays, which are mechanically and electrically connected to a main printed circuit board via first terminals and second terminals, and at least one flat conductor for conducting current between the at least two series connected relays. The flat conductor is mechanically connected to the main printed circuit board and electrically and thermally connected to the first terminals of the relays, and the at least one flat conductor is configured to dissipate heat produced during operation of the relays.
    Type: Grant

  • DC-DC converter having partial DC input conversion
    Patent number: 8817492
    Abstract: A DC/DC converter includes two input terminals for a DC input voltage, two output terminals for a DC output voltage, an inverter converting a DC voltage into an AC voltage, and a rectifier converting an AC voltage from the inverter into a DC voltage between a first one of the input terminals and a first one of the output terminals. At least one galvanically isolating element is arranged between the output of the inverter and the input of the rectifier, and a capacitance is coupled between the output terminals. The inverter converts a partial DC voltage, being smaller than the full DC input voltage, across a capacitance between the second one of the input terminals and the second one of the output terminals.
