Abstract
The present disclosure provides a power conversion device. The power conversion device includes the multi-level power factor correction circuit, the at least one output capacitor, the at least one input capacitor group, the first resonant conversion circuit and the second resonant conversion circuit. The at least one input capacitor group includes the first input capacitor and the second input capacitor. The at least one output capacitor is connected to an output part of the multi-level power factor correction circuit. The at least one input capacitor group is connected to the at least one output capacitor in parallel. The second input capacitor is connected to the first input capacitor in series. The input part of the first resonant conversion circuit is connected to first input capacitor in parallel. The input part of the second resonant conversion circuit is connected to the second input capacitor in parallel.
