boost converter

softswitching technique

Abstract—A new soft-switching boost converter is proposed in
this paper. The conventional boost converter generates switching
losses at turn ON and OFF, and this causes a reduction in the whole
system’s efficiency. The proposed boost converter utilizes a softswitching
method using an auxiliary circuit with a resonant inductor
and capacitor, auxiliary switch, and diodes. Therefore, the
proposed soft-switching boost converter reduces switching losses
more than the conventional hard-switching converter. The efficiency,
which is about 91% in hard switching, increases to about
96% in the proposed soft-switching converter. In this paper, the
performance of the proposed soft-switching boost converter is verified
through the theoretical analysis, simulation, and experimental
results.
