Abstract :
The paper presents an innovative PFC design that delivers 100 W of power at 96%-97% efficiency for nominal input range, in a low profile using a high frequency quasi-resonant interleaved boost topology, while maintaining a reasonable low cost of the ac-dc adapter. Theoretical considerations and practical results for high frequency interleaved boost converters are described. The goal of the design is maintaining a reasonable temperature rise of the case while delivering 100 W power in a reduced volume. The resulting product increases more than twice the power density compared to the standard notebook universal adapters.
