Abstract

This paper discusses about the effects of
switching frequency where reduction in losses is significant
to the converter’s performance. The proposed zero-voltageswitching
synchronous buck converter circuit is compared
with the conventional synchronous buck converter by
applying different frequency ranging from 250 kHz to 1.25
MHz. PSpice simulation is carried out using fixed delay
control scheme. It is found that the proposed circuit
improves the switching speed by at least 50 % in both turnoff
and turn-on transitions. In addition, more than 57 % in
switching losses have been reduced. Having a low body
diode conduction time, the proposed converter can
maintain low loss with minimized dead time delay,
indicating suitability in operating at high switching
frequency.
