An Interleaved Totem-Pole Power Factor Correction Converter
This paper explains about basic working principles, implementation problems, and experimental results of a new power factor correction (PFC) topology. In this proposed topology, a totem-pole boost PFC circuit that works under interleaved critical-conduction-mode (CRM) condition is presented. The circuit is developed towards high efficiency, high performance, lowcost, simple control scheme, and ...

متن کامل99% Efficiency True-Bridgeless Totem-Pole PFC Based on GaN HEMTs
Liang Zhou, member IEEE and YiFeng Wu, member IEEE Transphorm, Inc. 75 Castilian Dr., Goleta, CA, 93117 USA [email protected] Abstract: This paper presents a true bridgeless totem-pole Power-Factor-Correction (PFC) circuit using GaN HEMT. Enabled by a diode-free GaN power HEMT bridge with low reverse-recovery charge, very-high-efficiency single-phase AC-DC conversion is realized using a t...
متن کاملDevelopment of neurosurgery in southern California and the Los Angeles county/University of Southern California Medical Center.
The Los Angeles County General Hospital has played an integral role in the development of medicine and neurosurgery in Southern California. From its fledgling beginnings, the University of Southern California School of Medicine has been closely affiliated with the hospital, providing the predominant source of clinicians to care for and to utilize as a teaching resource the immense and varied pa...
متن کاملTotem-Pole Power-Factor-Correction Converter under Critical-Conduction-Mode Interleaved Operation
This paper proposes a new power-factor-correction (PFC) topology, and explains its operation principle, its control mechanism, related application problems followed by experimental results. In this proposed topology, critical-conduction-mode (CRM) interleaved technique is applied to a bridgeless PFC in order to achieve high efficiency by combining benefits of each topology. This application is ...
