Abstract
A single-stage AC to DC conversion device includes an energy storage unit, a magnetic unit, and a switch unit. The magnetic unit electrically connects the energy storage unit with the switch unit, and has a core, a first winding, a second winding, a third winding, and at least one output winding. The first winding couples with the core and transfers a first electric energy to the core. The second winding couples with the core and stores a second electric energy in the energy storage unit. The third winding couples with the core and transfers the second electric energy to the core. The output winding couples with the core that transfers the first electric energy and the second electric energy, and outputs a third electric energy through the output winding.
