Summary: | 碩士 === 東南科技大學 === 電機工程研究所 === 97 === This thesis presents design considerations of a high efficient
quasi-resonance flyback converter under soft switching QR mode operating in
Discontinuous conduction mode (DCM). Two kinds of control strategies for
QR flyback converters are described and compared. Two examples of 90W
(19Vdc/4.8 A) QR flyback converters are designed and examined under input
voltage of 90 ~ 264Vac / 50-60Hz. The efficiencies for the two converters are
quite the same as about 88% and their performance can actually match Energy
Star5 standard requirements.
