  • 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.
