Abstract
The boost topology is the most popular
topology used in power factor correction circuits. The
efficiency and performance of the boost converter
depends on the switching frequency affecting the
switching losses. At high frequency operations the
switching losses of the converter is considerable and
decreases the efficiency of the converter. To remove this
problem the converter is designed to operate at soft
switching mode operation. Soft switching mode operation
also removes the problem of EMI which is a result of
high frequency operation operating at hard switching. In
this study, there are given five different topologies of
DC-DC boost converters operating at soft switching. The
hard switching operation of the corresponding converters
are also given for the same load and operating conditions
and the effect of the soft switching in increasing the
efficiency of the converter is investigated. The given
converters are analyzed and their efficiencies are
compared. Auxiliary switches are also used in most soft
switching DC-DC boost converter. Though these
switches make the converter design a rather complicate
they have considerable effects on the performance of
boost converters.
