In the coming decades, nations will vigorously promote green and low-carbon smart cities to achieve carbon neutrality vision. Key components include smart grids, renewable energy power generation systems, electric vehicles, electric boats, and electric smart device charging stations. This global strategy effectively addresses energy shortages and environmental pollution. This project enhances the efficiency and performance of current quality compensation systems, wireless power transmission systems, and photovoltaic power generation systems through advanced power electronic circuits and key control technologies. This project develops a series of new controllers for the current quality compensation system, significantly improving accuracy, transient response, system robustness, and anti-disturbance capabilities. Notably, this project invents the first single-stage constant power wireless charging converter, which greatly increases the charging rate, achieves high efficiency, and ensures easy adaptation. Additionally, this project integrates the photovoltaic system with the above two systems to propose a new hybrid system, aiming to reduce system costs and expand functionality and operational range.
