Patents by Inventor Christian Beia

Christian Beia 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: 10333423
    Abstract: An electronic device includes a rectifier bridge that includes an input configured to be coupled to power over Ethernet (PoE) power sourcing equipment (PSE), and an output. A transistor is configured to selectively couple the output with a load. The electronic device includes a maintain power signature (MPS) device, and a control circuit. The control circuit is to maintain the transistor on when a load current is above a threshold, source current from the rectifier bridge to the MPS device when the load current is below the threshold, and switch the transistor to a diode configuration when the load current is below the threshold.
    Type: Grant

  • Patent number: 7710744
    Abstract: A method controls a Full Bridge converter with a Current-Doubler of the type including at least a first and a second half-bridges of diodes connected to respective control transistors. The method includes detecting a reference value, comparing, instant by instant, the reference value with an output voltage value of the converter, and carrying out a switching from a transfer phase to an energy recirculation phase in correspondence with instants when the output voltage value reaches the reference value.
