Patent number: 11848618Abstract: Pulse sharing control to enhance performance in multiple output power converters is described herein. During a switching cycle, an energy pulse is provided to more than one port (i.e., output) using pulse sharing transfer. Pulse sharing transfer may enhance performance by reducing audible noise due to subharmonics and by reducing a root mean square current of one or more secondary currents. A primary switch is closed to energize an energy transfer element via a primary current. Energy may be shared among a first load port on a first circuit path via a first secondary current and among a second load port on a second circuit path via a second secondary current.Type: GrantFiled: October 3, 2022Date of Patent: December 19, 2023Assignee: POWER INTEGRATIONS, INC.Inventors: Yi Li, Antonius Jacobus Johannes Werner, David Michael Hugh Matthews

Patent number: 11342856Abstract: A switched mode power converter has an energy transfer element that delivers an output signal to a load. A power switching device coupled to the primary side of the energy transfer element regulates a transfer of energy to the load. A secondary controller is coupled to receive a feedback signal and output a pulsed signal in response thereto. A primary controller is coupled to receive the pulsed signal and output a drive signal in response thereto, the drive signal being coupled to control switching of the power switching device. A compensation circuit generates an adaptively compensated signal synchronous with the pulsed signal. The adaptively compensated signal has a parameter that is adaptively adjusted in response to a comparison of the feedback signal with a threshold reference signal. The parameter converges towards a final value that produces a desired level of the output signal.Type: GrantFiled: April 9, 2019Date of Patent: May 24, 2022Assignee: POWER INTEGRATIONS, INC.Inventors: Giao Minh Pham, Vikram Balakrishnan, Arthur B.
