Abstract :
In this paper, a steady-state analysis for an isolated power factor corrected single-stage AC/DC converter with input stage operating in discontinuous and output stage in continuous conduction mode is presented. The steady state analysis and a proposed solution to control bus voltage without any extra feedback loop are provided and validated by simulation and experimental results.
