| Abstract: | The problem that the power factor of fence is low and harmonic contamination is bad becomes serious with the wide application of types of AC-DC converters. To solve the problem, a novel PFC circuit which uses the reference of phase-shifted soft-switching technoogy and combine the peculiarity of PFC circuit is given. The operating principium and process of this PFC cireuit is analyzed. This PFC cireuit can rectify the powr factor and achieve the conert AC to DC. it is a single isolated sof-switching PFC cireuit which can be widely used in the field of galvanization, electroanalysis, communications, and so on. |
