Power Electronics for Fast EV Charger

One of the main requirements for widespread use of electric vehicles is an accessible charging infrastructure. Governments and industries worldwide are preparing to invest in charging infrastructure but the critical points of the product decision are costs, power and reliability. SEMIKRON offers a comprehensive portfolio of products that meet the needs of fast charger equipment from 22kW to 450kW. With the latest technologies – such as wide-bandgap semiconductors – as well as new topologies, e.g. three-level, we achieve the best performance for your product.
