This document is an engineering report describing a PFC power supply utilizing a HiperPFS PFS714EG integrated PFC controller. This power supply is intended as a general purpose evaluation platform that operates from universal input and provides a regulated 380 V DC output voltage and a continuous output power of 347 W.
This power supply can deliver the rated power at 110 VAC or higher at a room temperature of 25 ºC. For operation at higher temperatures or lower input voltages, use of forced air cooling is recommended.
The use of CAPZero eliminates the static loss of R1 and R3, reducing standby and no-load input.
