How to drive LEDs with power factor correction in a single stage

July 16, 2014 1:47 pm | by Brian King, Texas Instruments, www.ti.com | Texas Instruments | Blogs | Comments

A PFC-SEPIC converter can be controlled using a traditional PFC-boost controller. An important characteristic of the SEPIC is the lack of isolation.  This limits the use of this topology to applications that don’t require safety isolation.  Think about applications that are completely sealed with no user-accessible energized parts, like street lights and high-bay lighting.
