A New Transformer-Less Single Switch Boost DC-DC Converter with Lower Stress

This paper presents a new transformer-less single switch structure for boost dc-dc converter with less stress. This proposed converter is introduced by using voltage-lift (VL) technique. In VL technique, the operating of a dc-dc converter completed using features of storage elements. In this paper, the voltage and current relations of proposed converter are extracted in continuous current mode (CCM). After, the voltage and current gains of the proposed converter are calculated in CCM. Then, the current and voltage stress of switch are analyzed. The compression of the proposed converter and some other boost dc-dc converter are also presented. The simulation results of proposed converter in CCM are done by PSCAD/EMTDC software to validity of theoretical concepts.
