PFC CCM Boost Converter Design Guide
Design guide for a 1200 W CCM PFC boost converter using the ICE3PCS01G controller and IPW65R045C7 CoolMOS, including design equations, layout, and a bill of materials.
Overview
This application note provides a comprehensive design methodology for a Power Factor Correction (PFC) Continuous Conduction Mode (CCM) boost converter. It details a 1200 W design example featuring the Infineon ICE3PCS01G controller and IPW65R045C7 CoolMOS MOSFET. The document covers power stage design equations, loss modeling, component selection for semiconductors and passives, and experimental results for a system with 85-265 VAC input and 400 VDC output. It includes technical schematics, PCB layout guidance, and a full bill of materials listing components such as Magnetics Inc. 77083A7 cores and Vishay GSIB2580 rectifiers.
Use Cases
- High-power AC-DC power supply design
- Server and telecom power systems
