The PFC circuit in the existing AC/DC Converter is a Two-stage power
conversion method which controls a Power Factor Correction and output
voltage respectively. But there are disadvantages. The first, that is costly and
complex because of high parts count. The second, that is low efficiency due
to separate power conversion circuit.
So, this paper applies the Single-stage PFC circuit to a low power Flyback
Converter and verifies validity through manufacture of experimental SMPS of 30 W degree.
