dc.description.abstractIn this thesis work, optimization of a power supply is done. This is done by employing a variable switching frequency (VSF) algorithm to ensure the soft switching of a full bridge zero voltage PWM switched converter while keeping the output waveform quality. Also a reduction of the wire losses of the output filter inductor has been achieved by employing Litz wires. It was found out that by using the VSF algorithm the switching losses were decreased. Moreover, by employing the VSF algorithm, the harmonic content of the output voltage of the full bridge has become more homogeneous throughout the frequency range. In addition to these, it was found out that the use of the solid wires introduces high AC resistance in the inspected frequency range. Accordingly, by employing the Litz wire this AC resistance can be decreased and the RI2 losses of the winding of the inductor can be reduced.
