Wireless power transfer (WPT) via magnetic coupling can have both the transmitter and receiver insulated and contactless, and thus shows versatility in both static and dynamic WPT applications under hostile environments where a physical connection is inconvenient or impossible. However, as a high-order resonant converter, it is challenging for a WPT converter to achieve wide-range outputs while maintaining high efficiency. This tutorial starts with this challenging issue, followed by an efficiency optimization principle and several methods for simultaneously achieving wide-range outputs and good efficiency. These methods will share ideas of load-independent-transfer characteristics, linear transfer functions, active rectification, active compensation, and so on. A thorough introduction to these methods will be provided with an emphasis on the achievement of stable output regulation and maximum efficiency tracking against variations of coupling coefficient and load condition, which typically occur in dynamic WPT application scenarios. This tutorial will touch on the topic of development for a wireless interface for future grid-to-vehicle and vehicle-to-grid operations. A summary and conclusions will be drawn toward the end of the tutorial.
