Advanced Inverter Technologies: Enhancing Efficiency in Power Conversion Systems

Dear Colleagues,

Power converter technologies are a key enabling technique for efficient management and conversion of electrical power, serving as the backbone of many modern applications. These include renewable energy generation, energy storage, flexible transmission, transportation, machine drives, and so on. As with much technology, synergistic factors such as device physics, materials development, and digital control, come together to make entire new applications feasible. Essential elements in a power converter system are power semiconductor devices functioning as switches, often with many configured in tandem, and complex optimisations, balancing cost and performance, which should be considered when choosing device technology, size and circuit topology. Another crucial technology in converters is signal processing, which implements switching modulation and dynamic control functions. Passive components remain important in connection filters and as high-frequency transformers in many converters and are greatly affected by material considerations.

The advancement of power converter technology is continuing, with new challenges and opportunities evolving, focusing specifically on advanced converter topologies, materials science, component design, system integration and control. The aim of this Special Issue is to provide a forum for researchers and practical engineers in the power electronic field to present, review and analyse the recent advancements in these aspects.
