Summary

This chapter introduces the principles and mechanisms behind wireless power transfer (WPT), focusing on inductive power transfer systems. It begins with the historical development of WPT and then delves into the fundamental aspects of inductive power transfer, including general configurations. The chapter provides a detailed examination of theoretical models, such as the loosely coupled transformer model, T-model, and M-model, and compares their effectiveness. It further explores compensation networks, including series and parallel types, and discusses transmission performance metrics such as output power, transfer efficiency, and their interrelationships. This comprehensive overview establishes the foundational knowledge necessary for understanding advanced WPT systems.

Content Navigation

Table of contents navigation
Allows you to navigate directly to chapters, sections, or non‐text items through a linked table of contents, reducing the need for extensive scrolling.
Index navigation
Provides an interactive index, letting you go straight to where a term or subject appears in the text without manual searching.

Reading Order & Textual Equivalents

Single logical reading order
You will encounter all content (including footnotes, captions, etc.) in a clear, sequential flow, making it easier to follow with assistive tools like screen readers.
Short alternative textual descriptions
You get concise descriptions (for images, charts, or media clips), ensuring you do not miss crucial information when visual or audio elements are not accessible.
Full alternative textual descriptions
You get more than just short alt text: you have comprehensive text equivalents, transcripts, captions, or audio descriptions for substantial non‐text content, which is especially helpful for complex visuals or multimedia.

Visual Accessibility

Use of colour is not sole means of conveying information
You will still understand key ideas or prompts without relying solely on colour, which is especially helpful if you have colour vision deficiencies.
Use of high contrast between text and background colour
You benefit from high‐contrast text, which improves legibility if you have low vision or if you are reading in less‐than‐ideal lighting conditions.
