DER-547- 275W PFC Front-End

Overview

This engineering report describes a PFC power supply using the HiperPFS-4 PFS7627H PFC controller with integrated power MOSFET and external boost diode. This power supply is designed as a general purpose platform, operating from 100 VAC to 300 VAC input voltage, and provides a stable 440 V DC output voltage and 275 W of continuous output power. The DER-547 power supply is designed to operate under forced air conditions with a cooling effect of greater than 200 LFM for all input and load conditions (up to rated maximum ambient temperature of 50°C). This document contains power supply specifications, schematics, bill of materials, inductor documentation, printed circuit layout and performance data
