Patents by Inventor Giorgio Augusto Mauri

Giorgio Augusto Mauri has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10756632
    Abstract: A DC power supply includes a point-of-load (PoL) regulator providing power to a load with a desired efficiency only when a PoL input voltage is in a first sub-range of a specified larger system input voltage range. The supply has an auxiliary circuit with an output in series with the supply input, generating an auxiliary voltage and adding it to the DC supply voltage to form a boosted supply voltage. Switching circuitry connects the supply input to the PoL input to apply a DC supply voltage as the PoL input voltage when the supply voltage is in the first sub-range, and connects the output of the auxiliary circuit to the PoL input to apply the boosted supply voltage as the PoL input voltage when the supply voltage is outside the first sub-range, maintaining the PoL input voltage within the first sub-range.

  • Patent number: 10756624
    Abstract: A DC-DC converter suitable for conversion of high input voltages to regulated low output voltages at very high output currents has a cascade of stages including a buck regulation stage, an unregulated switched capacitor voltage doubler, and an unregulated voltage isolation stage. These three stages are merged in a single switching structure so that each stage optimally performs its respective function while also taking advantage of characteristics and features of neighboring stages.
