Abstract
A boost power conversion circuit includes an inductor, a first switch module, a second switch module, a first unilateral conduction component, a second unilateral conduction component, a flying capacitor, an upper bus capacitor, a lower bus capacitor, and a third unilateral conduction component. The power supply, the inductor, the first switch module, and the second switch module are connected in series to form a loop. The first unilateral conduction component, the second unilateral conduction component, the upper bus capacitor and the lower bus capacitor are connected in series. The flying capacitor is electrically connected between a reverse cut-off end of the first unilateral conduction component and a forward conduction end of the second unilateral conduction component. The third unilateral conduction component is configured to clamp a voltage stress of the second switch module to a lower-bus voltage.
