Are there high-frequency inverters for WPT systems?

This paper reviews the high-frequency inverters for WPT systems, summarizes the derived topologies based on power amplifiers and H-bridge inverters, investigates the main factors restricting the development of high-frequency inverters, and analyzes the research directions for future development. 1. Introduction

What is a high frequency inverter?

In many applications, it is important for an inverter to be lightweight and of a relatively small size. This can be achieved by using a High-Frequency Inverter that involves an isolated DC-DC stage (Voltage Fed Push-Pull/Full Bridge) and the DC-AC section, which provides the AC output.

Can Gan be used for high-frequency inverters in WPT systems?

This research was finally successfully applied to the CPT system . The University of Tennessee validated the performance enhancement of GaN for high-frequency inverters in WPT systems by accurately modeling high-frequency transients in the junction capacitance of GaN devices with good heat dissipation design.

What inverters are used in high-power WPT systems?

Currently, the most widely used inverters in high-power WPT systems are H-bridge Inverters, and various types of new topologies have been derived depending on the application requirements. In addition, for high-frequency applications, the distribution of parasitic parameters in the circuits and their effects also need to be paid attention to.
