Concept of Single Stage PFC
Conventional Solution
1st Stage: PFC 2nd Stage: DC-DC Converter
Single Stage Solution ™ Isolation
Flyback < 100W ™ Non-isolation
Boost Buck-boost < 250W Cuk Sepic
™ Parallel Operation> 250W
- Merits: Low-cost solution ( BOM reduction of 5 components ) - Demerits: Lower Power Factor, Higher rating components especially output capacitance.
