Innovations in Power Electronics for Efficient Energy Conversion

Abstract

Power electronics technology plays a pivotal role in modern electrical engineering by facilitating efficient energy conversion, regulation, and control. This paper reviews the latest advancements in power electronic devices and converter topologies, including wide bandgap semiconductor devices such as Silicon Carbide (SiC) and Gallium Nitride (GaN). These devices offer higher efficiency, faster switching speeds, and improved thermal performance compared to traditional silicon-based components. The paper further investigates the application of multilevel inverters, modular multilevel converters, and resonant converters in renewable energy integration, electric vehicle (EV) charging systems, and industrial drives. Key challenges, including electromagnetic interference (EMI), thermal management, and system reliability, are analyzed, alongside emerging solutions such as advanced cooling techniques and intelligent control strategies.
