隔离式电源转换器的趋势与新兴技术

Isolated power converters have emerged as an active research topic in power integrated circuit(IC)design.Reflect-ing this growing interest,ISSCC 2025 has featured a dedi-cated session on"Isolated Power and Gate Drivers".These con-verters enable safe and reliable power delivery across volt-age domains and are widely used in renewable energy,elec-tric vehicles,and telecommunications.Galvanic isolation pre-vents surge currents and ground loop issues in harsh high-volt-age environments.As demand grows for compact,efficient,and high-power-density solutions,fully integrated architec-tures featuring on-chip transformers are increasingly favored over traditional module-based designs,offering>5 kV isola-tion with a smaller footprint and lower system cost[1].
