Patent number: 10256741Abstract: 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: GrantFiled: September 6, 2017Date of Patent: April 9, 2019Assignee: NEXGEN POWER SYSTEMS, INC.Inventors: Antoin Russell, Alberto Doronzo

Publication number: 20180048225Abstract: 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.Type: ApplicationFiled: May 30, 2017Publication date: February 15, 2018Applicant: Nexgen Power Systems, Inc.Inventor: Alberto Doronzo
