Ricardo Bernado Roldan, JR. 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: 11942870
    Abstract: A power supply receives AC power and generates a DC output voltage. The power supply may be divided into a primary section that converts AC power to a relatively high DC voltage. A secondary section converts this relatively high DC voltage into a well-regulated lower DC voltage. In an embodiment, the current and/or power supplied by the primary to the secondary side is used by the secondary side in a closed-loop feedback system to limit the current drawn by the secondary side to a configurable value.
    Type: Grant
    Filed: February 28, 2023
    Date of Patent: March 26, 2024
    Assignee: Astec International Limited

  • Patent number: 11682921
    Abstract: A power system includes first and second power supplies, and a control circuit. The control circuit is configured to control the first power supply to regulate its output voltage at a first value, enable the second power supply, increase the output voltage of the first power supply to a second value in response to the second power supply being enabled, increase an output voltage of the second power supply to a third value, and decrease an output current of the first power supply and increase an output current of the second power supply to transition between electrically powering the load with the first power supply and electrically powering the load with the second power supply. Other example power system and methods for controlling a power transition between power supplies are also disclosed.
