Bezdrátová nabíječka podle standardu NFC Forum WLC 2.0

Abstract

This diploma thesis is focused on wireless charging technology according to the Wireless Charing 2.0 standard by the NFC Forum and the design of an ASIC circuit of a device functioning as a listener, where the primary emphasis is placed on the digital design of this circuit. In the beginning the work deals with a general theory, gradually discussing all the standards from the NFC Forum that are necessary for the control protocol design according to the Wireless Charging 2.0. Subsequently, the analysis of a real communication in the development kit for this standard is conducted, based on which the system design of the digital circuit is made. The designed circuit is described by VHDL language and verified by running the basic simulations to check the functionality of the designed parts of the circuit. In the final part of the thesis, a prototype module with the proposed system is fabricated, implemented in an FPGA with a connected battery charger circuit and its functionality is tested in practice.

Tato diplomová práce je zaměřena na technologii bezdrátového nabíjení podle standardu Wireless Charging 2.0 od standardizační organizace NFC Forum a na návrh obvodu ASIC pro zařízení ve funkci přijímače, kdy je největší důraz kladen na návrh digitální části daného obvodu. V úvodu se práce zabývá obecnou teorií, kde jsou postupně probrány všechny normy od společnosti NFC Forum potřebné pro návrh řízení kontrolního protokolu podle standardu Wireless Charging 2.0. Následně je provedena analýza reálné komunikace vývojové sady určené pro tento standard, na jejímž základě je proveden systémový návrh digitálního obvodu. Navržený obvod je poté popsán pomocí jazyka VHDL a následně je simulacemi ověřena základní funkčnost jednotlivých bloků. V závěru práce je zhotoven prototypový modul s navrženým systémem, který je implementován do obvodu FPGA s připojeným nabíjecím obvodem a jehož funkcionalita je poté otestována v praxi.
