  • System and method to improve standby efficiency of LLC converter
    Patent number: 10079540
    Abstract: A system includes an LLC converter to convert an input DC voltage to an output DC voltage. A burst generator generates a switching signal having a burst time and a sleep time to operate the LLC converter when output load current of the LLC converter is below a predetermined threshold. A burst power calculator adjusts the sleep time for the switching signal such that output power of the LLC converter during the burst time is held substantially constant with respect to changes in the output load current.
    Type: Grant
    Filed: March 14, 2017
    Date of Patent: September 18, 2018
    Assignee: Texas Instruments Incorporated
    Inventors: Joe M. Leisten, Dermot Dobbyn, Vasco Santos
