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
The buck–boost inverter can convert the PV module’s output voltage to a high-frequency square wave (HFSWV) and can enhance maximum power point tracking (MPPT) even under large PV voltage variations. The high-frequency transformer gives galvanic isolation for the system, which decreases the leakage current and improves the system power quality.
A high-frequency inverter circuit is a combination of a low-frequency power inverter circuit and RF power amplifier circuit, so, drawing on various types of switching mode power amplifiers in RF circuits to be applied to the WPT system is a very sensible choice.
Our BESS energy storage systems and photovoltaic foldable container solutions are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
