Vocational Education from a Cross-national Perspective:Comparative Analysis of China,Germany,and the United States,with a Case Study of Zhaixing

This study delves into the current state and challenges of vocational education through a comparative study of cross-national vocational education and an analysis of the Zhaixing Academy case.The research reveals that vocational education reform can draw on the experiences of the German dual system,American community colleges,and Chinese vocational education reforms,with a focus on informal education pathways,practice-oriented teaching,and flexible training methods.The Zhaixing Academy case demonstrates the application of practice-oriented teaching approaches in the field of vocational education,emphasizing individual student development needs and the advantages of education outside formal institutions,offering new insights and references for the current Chinese education system.The study proposes that governments and education departments should increase investment in vocational education,encourage collaboration between enterprises and vocational education institutions,and support innovative practice-oriented education.In the future,Zhaixing Academy can continue to focus on education reform,expand the realm of practice-oriented education,promote its educational philosophy and methods,and contribute to the diversification and sustainable development of education.

Application of Power Electronics Converters in Renewable Energy

Against the backdrop of global energy shortages and increasingly severe environmental pollution,renewable energy is gradually becoming a significant direction for future energy development.Power electronics converters,as the core technology for energy conversion and control,play a crucial role in enhancing the efficiency and stability of renewable energy systems.This paper explores the basic principles and functions of power electronics converters and their specific applications in photovoltaic power generation,wind power generation,and energy storage systems.Additionally,it analyzes the current innovations in high-efficiency energy conversion,multilevel conversion technology,and the application of new materials and devices.By studying these technologies,the aim is to promote the widespread application of power electronics converters in renewable energy systems and provide theoretical and technical support for achieving sustainable energy development.
