PFC Design – Maximizing Efficiency and Lowering Cost with GaN Transistors

Achieving efficiencies greater than 98% in conventional Power Factor Correction (PFC) circuits is challenging. The major hurdle is fixed diode bridge losses. An option to overcome this is to use silicon MOSFETs in place of the diodes to achieve efficiencies of 99% or more. However, this BTPPFC approach suffers from poor reverse recovery performance, is suitable only for low power, and requires complicated control parameters.
