| Abstract |
This paper introduces a new scheme for a single-stage unity power factor corrector. This structure is composed of a buck-boost converter cell followed by a series/parallel converter combined into a single stage. A very interesting property of the buck-boost allows the attainment of a unity power factor when it works in discontinuous current mode with a
constant duty ratio. A single output voltage control loop and a pulse width modulation control strategy at constant frequency ensure a minimum of circuit complexity. |
