A novel all soft switching DC converter with power factor correction

Principle of synthesizing single-stage converters (SSC's) for off-line applications is presented in the paper. The principle is primarily based on the concept of dither effect, from which power factor corrector (PFC) cells comprising energy buffers and high frequency dither signals are introduced. Properly selecting an eligible PFC cell and inserting it in between input rectifier and dc-link capacitor can yield an SSC. In the paper, principle and configuration of PFC cells are addressed; thus, quite a few families of SSC's for off-line applications can be synthesized from the derived PFC cells. With this principle, not only the SSC's discussed in literature can be developed alternatively, but novel SSC's can be synthesized. Most of the SSC's have been proved in the literature to be feasible in applications with moderate power levels.
