| Summary: | 碩士 === 國立海洋大學 === 電機工程學系 === 84 === The zero-current-switched quasi-resonant converter is derived
from the com-binations of conventional PWM converters and
resonant principles,by adding a L-C resonant element to the
switch of a PWM converter,so that in the switch highvoltage and
high current are not present at the same,since the turn-off loss
iseliminated by turning off the switch at zero current.This
technique is referredto as the zero-current-switching technique.
In this report,We derive some transfer functions of buck zero-
current-switchedquasi-resonant converter,basedonVorperian's
resonant switch model,so as to realize the stability analysis of
the system.Finally,some selected experimental results presented
to verify theproposed theory.
