In this paper, a multiphase boost converter is proposed to achieve high voltage gain and high power gain. The proposed converter operates in continuous conduction mode (CCM) with soft switching of main and auxiliary devices. The transformer in a conventional converter is replaced by an auxiliary circuit which provides the desired voltage and power levels. The zero voltage switching (ZVS) and ze...

The fundamental operational parameter that controls the losses In series resonant converters was round to be the (reflected) DC voltage transfer ratio. Losses which are a function of the average current (such as conduction losses of IGBTs and diodes) are independent of the s\vltchlng frequency. Losses which are associated with the rms current are a function of both the (reflected) DC voltage ra...

So, the primary side switches utilize zero voltage sw...

A novel topology for a soft-switching buck dc– dc converter with a coupled inductor is proposed. The soft-switching buck converter has advantages over the traditional hardswitching converters. The most significant advantage is that it offers a lower switching loss. This converter operates under a zero-current switching condition at turn on and a zero-voltage switching condition at turn off. It ...
