Key Technologies and New Developments of Stationary/Dynamic Wireless Power Transfer

In the last few decades, wireless power transfer (WPT) is widely used in various applications due to its safety and reliability, and has become the trend of power supply in the future. However, there are still some challenges and problems to be solved in practical applications, such as large current stress with single phase-shift control, multiple outputs for driving multi-string LEDs, power pulsation phenomenon or power null phenomenon in dynamic WPT (DWPT) system. This tutorial will introduce these problems and present the corresponding solutions in detail.
