Conclusions
This user guide describes the implementation of an analog-controlled, single-phase, two-channel interleaved
PFC converter that operates in continuous conduction mode. This interleaved PFC converter achieves a peak
efficiency of 97.804% by using an Infineon 650 V
TRENCHSTOP™ 5 WR5 IGBT IKW40N65WR5
and rapid1 power
silicon diode IDW60C65D1.
The EVAL-PFC5KIKWWR5SYS board has been tested using a programmable AC source and electronic load to
demonstrate the key performance and behaviors in PFC operation.
Customers can also furthe increase the switching frequency to decrease the size and cost of the inductors, or
extend the converter input voltage from 85 V
AC
to 264V
AC.
External parameter settings of resistors and capacitors
of UCC28070 are also needed as an optimizations to the new requirments.
