During the visit, the delegation gained a comprehensive overview of Donghai Semiconductor’s corporate culture, development milestones, core products, and technology applications, with particular interest in the company’s achievements in innovation-driven R&D and intelligent manufacturing.

Electric vehicles (EVs) have rapidly emerged as a cornerstone of sustainable transportation, driven by global efforts to reduce carbon emissions and reliance on fossil fuels. As consumer demand for cleaner, smarter, and more efficient mobility solutions grows, the technology inside EVs continues to evolve at an unprecedented pace.

The 18th SNEC International Photovoltaic Power Generation and Smart Energy Exhibition 2025 concluded successfully on June 13, 2025, at the National Exhibition and Convention Center in Shanghai. As one of the most influential events in the global renewable energy industry, this year’s SNEC attracted thousands of energy professionals, industry leaders, and innovative technology providers from around the world.

Understanding the difference between IGBT and MOSFET is crucial for engineers, designers, and technical professionals working with modern power electronics. Both IGBTs and MOSFETs are vital building blocks in a wide range of applications, from renewable energy systems to industrial automation and electric vehicles. Knowing when to choose an IGBT and when to use a MOSFET can improve efficiency, reliability, and cost-effectiveness.

When it comes to modern electronics, the MOSFET​ plays a vital role in everything from mobile phones to electric vehicles. A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is the backbone of power switching and amplification in electronic circuits. Whether you're designing a solar inverter, building a lithium battery management system, or working on an electric vehicle charger, understanding how a MOSFET works—and more specifically, the three modes of operation—is essential.

IntroductionIn the realm of electronic components, the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) has emerged as a fundamental building block in modern circuitry. While traditional bipolar junction transistors (BJTs) have played a significant role in the development of electronic dev
