Patent number: 11557960Abstract: Adaptive enabling and disabling is described for valley switching in a power factor correction boost converter. In one example, a boost converter control system includes an amplitude detector to receive an amplitude signal from a boost converter that is related to ringing of the boost converter output. The amplitude detector determines the ringing amplitude. A valley switching controller compares the ringing amplitude to a first high amplitude threshold when valley switching is enabled and generates a valley switching disable signal if the ringing amplitude is below the first high amplitude threshold. A cycle controller coupled to the boost converter generates a drive signal to control switching of the boost converter and coupled to the valley switching controller receives the valley switching disable signal to generate the drive signal without valley switching in response to the valley switching disable signal.Type: GrantFiled: September 30, 2021Date of Patent: January 17, 2023Assignee: NXP USA, Inc.Inventors: Remco Twelkemeijer, Wilhelmus Hinderikus Maria Langeslag, Peter Theodorus Johannes Degen

Patent number: 11011995Abstract: A PWM power supply controllers are typically applied for a single output power supply. For specific applications, like LCD TV's, dual outputs are required. As a preference to only regulate one output, the performance of the system suffers when the outputs are unequally loaded. The disclosure describes a way to balance the outputs, such that when the output are unequally loaded, additional outputs are still accurately regulated.Type: GrantFiled: June 15, 2017Date of Patent: May 18, 2021Assignee: NXP B.V.Inventor: Peter Theodorus Johannes Degen
