The Role of Hybrid Transformers in Sustainable Energy Automation

This chapter provides a comprehensive examination of Hybrid Transformers (HTs) as key components in the transition to sustainable and intelligent energy systems. It begins with an overview of the background and importance of HTs, emphasizing their role in improving grid efficiency, power quality, and renewable energy integration. Structural design and operating principles are analyzed, including series, parallel, and multilevel configurations. The chapter also explores enabling technologies such as wide bandgap semiconductors, modular power converters, and AI- based control algorithms. Performance and efficiency analyses address core, conductor, and switching loss reduction strategies. Furthermore, the chapter highlights the contributions of HTs to smart grids, energy management systems, and renewable energy- storage integration. It concludes by discussing key technical challenges, offering potential solutions, and identifying future research directions to support the development and deployment of HTs in advanced power infrastructures. © 2026 by IGI Global Scientific Publishing.
