Patent number: 11394241Abstract: The invention relates to a resonator of a wireless power transfer system (1), including a magnetic core in the form of an H-core with two yokes and at least one limb (52) connecting the yokes where a winding (53) is wound on the limb (52) of the core. The winding (53) includes a PCB (56.1) on one side of the limb (52) and a PCB (56.2) on another side of the limb (52) where the turns of the coil are formed by traces on the first PCB (56.1) and on the second PCB (56.2) that are connected to each other by soldering pins (57) that are soldered into corresponding holes of the PCBs (56.1, 56.2). The traces on the PCBs (56.1, 56.2) may be provided on a single conductive layer of the PCBs (56.1, 56.2) or the PCBs may be multilayer PBS, where each turn section between two soldering pins (57) on one of the PCBs (56.1, 56.2) may include several strands including one or more traces on one or more conductive layers.Type: GrantFiled: August 19, 2020Date of Patent: July 19, 2022Assignee: DELTA ELECTRONICS (THAILAND) PUBLIC CO., LTD.Inventors: Tobias Grote, Philipp Rehlaender, Hugues Njiende T., Sergey Tikhonov

Patent number: 8278899Abstract: A digital slope compensation apparatus and method for a switched-mode power supply use a sensor for sensing and generating an analog inductor current (iL) of the switched-mode power supply, a comparator (2) for generating a trigger signal according to a comparison of an analog current threshold level and the analog inductor current (iL), and a pulse width modulator (PWM) for controlling the operation of a switched-mode power supply, wherein the pulse width modulator (PWM) is arranged to be triggered by the trigger signal of the comparator. A first analog to digital converter is arranged for converting an analog output voltage (Vout) of the switched-mode power supply into a digital output voltage, means are arranged for transforming the digital output voltage into a digital current threshold level (icmp) and a digital to analog converter is arranged for generating the analog current threshold level according to the digital current threshold level (icmp).Type: GrantFiled: August 30, 2010Date of Patent: October 2, 2012Assignee: DET International Holding LimitedInventors: Frank Schafmeister, Tobias Grote
