Patent number: 9748844Abstract: An electronic device includes a controller configured to regulate one or more voltages or currents of a power converter. The controller is configured to receive an input voltage of the power converter, determine whether the power converter is operating in a first mode of operation or a second mode of operation based at least in part on the input voltage, generate a multiplier reference signal for the power converter based on whether the power converter is operating in the first mode of operation or the second mode of operation, and adjust an input current of the power converter based at least in part on the multiplier reference signal. Adjusting the input current includes correcting the input current to be substantially identical in form to the input voltage.Type: GrantFiled: December 18, 2015Date of Patent: August 29, 2017Assignee: General Electric CompanyInventors: Ramanujam Ramabhadran, Jeffrey Joseph Nasadoski, Yehuda Daniel Levy, Shimon Khananshvili, Pradeep Vijayan, Bruce Richard Roberts
