Abstract

In this paper, Sigle Ended Primary Inductance Converter (SEPIC) is evaluated. at first, the classical SEPIC circuit and few modified SEPIC converters with some snubber cells are examined. These snubber circuits are used to obtain turn-on and turn-off Soft Switching for all input voltage ranges and output power variation. Using Soft Switching technique limits the di/dt at the switch turn-on instant and zero-current switching (ZCS) is obtained. It also can limit the dv/dt at the switch turn-on instant. Since it is better to electrically separate the input and output parts of the circuit with a transformer to increase the voltage gain and to isolate the circuit, in the following, an isolated SEPIC converter is studied. In this case, with the presence of the transformer, the voltage stress on the main switch becomes more intense and the need for snubber circuits becomes necessary. For this reason, some snubber cells are introduced and compared with each other. These circuits were analysed and simulated by “ Orcad Capture” software.
