Active Power factor corrected AC-DC converters in the power range of 500 watts and above are mostly accomplished in a two-stage process. The front end is non-isolated boost regulator working in CCM and the second stage is a DC-DC converter with isolation. This process is less efficient, complex and consumes more area. The front end PFC in CCM is a major source of EMI requiring heavy line filters to meet the international interface specifications. A novel single-stage AC-DC converter for the output power of 1KW is proposed here, which has many advantages such as Single active switch, completely soft switched and isolated. The new configuration is fabricated and tested for all the parameters. A near unity PF is achieved and the worst case efficiency is recorded to be 94%. All the test data are presented.
