  • Patent number: 10256741
    Abstract: An embodiment of a resonant converter includes having resonant circuitry having inductive and capacitive elements configured to create electrical resonance when an input voltage is applied and a synchronous rectifier coupled between at least a portion of the resonant circuitry and an output of the resonant converter. The synchronous rectifier includes a diode, and an electrical switch. Control circuitry is configured to operate the electrical switch such that the electrical switch is turned on when there is substantially no voltage across the diode and current flow in the diode is positive in a direction from anode to cathode.
    Type: Grant

  • Publication number: 20180048225
    Abstract: An AC-DC converter configured to convert an input AC signal to an output DC signal is disclosed. The AC-DC converter includes an inductor and first and second transistors, where the inductor and first and second transistors are connected in series with one another. The input AC signal is applied across the series connected inductor and first and second transistors, and the series connected inductor and first and second transistors is configured to generate a secondary AC signal based on the AC input signal. The AC-DC converter also includes a rectifier, configured to rectify a signal based on the secondary AC signal to generate a substantially DC output signal based on the AC input signal.

  • Publication number: 20150357919
    Abstract: A variable output power supply includes a power unit comprising a housing including an output port and a controller disposed in the housing and in communication with the output port. The variable output power supply also includes a power cable. The controller is operable to modify operation of the output port in response, at least in part, to insertion of the power cable in the output port.

  • Publication number: 20150263628
    Abstract: An embodiment of non-isolated resonant converter includes resonant circuitry having inductive and capacitive elements configured to create electrical resonance when an input voltage is applied, a first electrical switch coupled to the resonant circuitry such that the first electrical switch conducts a current of the resonant circuitry, and voltage-monitoring circuitry coupled to the resonant circuitry and configured to determine when there is substantially no voltage across the first electrical switch. The non-isolated resonant converter further includes control circuitry configured to receive an input from the voltage-monitoring circuitry, and operate the first electrical switch. The control circuitry is configured to turn the first electrical switch on when substantially no voltage is detected across the first electrical switch.
