| dc.description.abstract-translated | ncreasing use of rectifiers causes harmonics pollution in networks. So use of power factor correction (PFC) in converters is inevitable. For reducing weight and volume of converters, designers try to increase switching frequency. The switching losses and conduction losses are two sources of losses in the switching power converter. Thus to reduce these losses, a new bridgeless soft switching PFC converter without any extra switch is introduced in this paper. A passive lossless snubber is used for bridgeless boost converter which can reduce the switching and conduction losses simultaneously. The proposed converter provides soft switching condition for all semiconductor elements. The proposed converter is analyzed theoretically and the design consideration are given. Then for a design example, the values of circuit elements are calculated. It is simulated by PSIM. Finally the efficiency comparison that is simulated by ORCAD software is presented. It shows that the proposed converter improve the efficiency at the nominal load in comparison with hard switching counterpart. | en |
