DER-274: 900W, 380V Out, 180 ~ 264VAC in


This document is an engineering report describing a PFC power supply utilizing a HiperPFS PFS729EG integrated PFC controller. This power supply is intended as a general purpose evaluation platform that operates from 180 VAC to 264 VAC input and provides a regulated 380 VDC output voltage and a continuous output power of 900 W.

This power supply can deliver the rated power at 230 VAC or higher input voltages at a room temperature of 25 ºC. For operation at higher ambient temperatures or lower input voltages, use of forced air cooling is recommended.

The document contains the power supply specification, schematic, bill of materials, inductor documentation, printed circuit layout, and performance data.
