Based on the impedance model, the oscillation mechanism of the island power system is analyzed. On the basis of traditional dual-loop control, an impedance reconstruction control of the source PWM inverter is proposed, which can effectively suppress the high-frequency oscillation of the island power system.
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
After adding impedance reconstruction control, the output voltages and currents of the source PWM inverter loaded with pure resistive load remain stable under different output power; when the load is a PWM rectifier, the high-frequency oscillation of the island power system is effectively suppressed.
The power supply topologies suitable for the High-Frequency Inverter includes push-pull, half-bridge and the full-bridge converter as the core operation occurs in both the quadrants, thereby, increasing the power handling capability to twice of that of the converters operating in single quadrant (forward and flyback converter).
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
