一种用于燃料电池UPS的集成PFC和DC-DC功能的前端变换器

This paper presents the development of a boost converter with integrated power factor correction (PFC) and dc-dc functions for a proton exchange membrane fuel cell (PEMFC) uninterruptable power supply (UPS). Through the use of a passive resonant soft-commutation cell, which besides providing improvements in efficiency and reduced electromagnetic interference, produces a naturally controlled superc...
