Simplifying Power Factor Correction in SMPS

by Jon Mark Hancock, Senior Applications Engineer, Infineon Technologies NA, San Jose, Calif., Power Electronics Technology, Oct 01 2004

Focus:
A continuous-conduction mode PFC controller with enhanced protection features is combined with a superjunction MOSFET and SiC Schottky to implement a PFC boost converter that is compact, highly efficient, and able to manage surge currents.

What you’ll learn:

• How to achieve small size and high efficiency in a PFC boost converter operating in continuous-conduction mode.
• How to implement a 650-W PFC boost converter based on Infineon's ICE1PCS01
