  • Digital controller based detection methods for adaptive mixed conduction mode power factor correction circuit
    Patent number: 8937469
    Abstract: Methods and apparatus for zero current detection and discontinuous conduction mode digital detection for a boost power factor correction converter based on a digital signal processor are disclosed. By effectively using resources in a processor with integrated high-speed comparators, simple detection can be accomplished with cost and performance over alternative detection methods. The methods and apparatus can be employed in an adaptive digital controller for mixed-conduction mode in the converter and can provide for lower total harmonic distortion and greater power factors than a non-adaptive controller.
    Type: Grant

  • System and Method for Data Transfer with a Battery Charger
    Publication number: 20140081940
    Abstract: A system and method for transferring data between a charging system comprising a data control module and a removable memory is provided. The method comprises the data control module detecting a connection with a removable memory module and identifying and selecting a file on the removable memory. The data control module then obtains the selected file from the removable memory.
