Publication number: 20240146203Abstract: Methods and apparatus for continuous conduction mode operation in multi-output power converters are described herein. During a switching cycle, secondary current may be delivered via a diode to a secondary output. Prior to beginning a subsequent switching cycle, a diverting current may be provided to a lower voltage secondary output on a parallel path. In this way diode current may be reduced to substantially zero prior to the subsequent switching cycle.Type: ApplicationFiled: October 4, 2023Publication date: May 2, 2024Applicant: POWER INTEGRATIONS, INC.Inventors: KARL MOORE, ANTONIUS JACOBUS JOHANNES WERNER

Patent number: 11927738Abstract: Described herein are systems and methods for assessing a biological sample. The methods include: characterizing a speckled pattern to be applied by a diffuser; positioning a biological sample relative to at least one coherent light source such that at least one coherent light source illuminates the biological sample; diffusing light produced by the at least one coherent light source; capturing a plurality of illuminated images with the embedded speckle pattern of the biological sample based on the diffused light; iteratively reconstructing the plurality of speckled illuminated images of the biological sample to recover an image stack of reconstructed images; stitching together each image in the image stack to create a whole slide image, wherein each image of the image stack at least partially overlaps with a neighboring image; and identifying one or more features of the biological sample. The methods may be performed by a near-field Fourier Ptychographic system.Type: GrantFiled: May 3, 2022Date of Patent: March 12, 2024Assignee: Pathware Inc.Inventors: Rodger Michael Moore, Cordero Derrell Core, Jaron Nathaniel Nix, Thomas Karl, Samantha Hastings, Samir Yhann

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.

Patent number: 11211870Abstract: Apparatus and methods for sequencing outputs in a multi-output power converter system are disclosed herein. During start-up multiple CC/CV outputs may be sequenced so that energy is first provided to a highest voltage secondary output and subsequently provided to a lowest voltage secondary output. Additionally, control may be exerted so as to concurrently and monotonically increase voltages during at least part of the start-up transient; and concurrent control may be further implemented using control circuitry and a variable reference generator. In some embodiments a variable reference may be generated from a capacitor voltage.Type: GrantFiled: January 16, 2019Date of Patent: December 28, 2021Assignee: POWER INTEGRATIONS, INC.Inventors: Karl Moore, Matthew David Waterson, Antonius Jacobus Johannes Werner
