Abstract
A power conversion system includes a power conversion circuit and a start circuit. The power conversion circuit includes a first terminal, a second terminal, an output capacitor, at switching unit, a flying capacitor and a magnetic element. The second switching unit includes two switch groups. The flying capacitor is connected between the first terminal and the second terminal. The magnetic element includes two first windings that are electromagnetically coupled with each other. A first one of the two first windings is electrically connected between one switch group and the second terminal of the power conversion circuit. A second one of the two first windings is electrically connected between the other switch group and the second terminal of the power conversion circuit. The start circuit includes a third winding, an inductor and at least one switch element. The third winding is electromagnetically coupled with the first windings.
