Abstract
A power conversion device is provided. The power conversion device is applied to a circuit topology and layout of the six-switch flying capacitor voltage reduction type conversion circuit which is applied to the intermediate bus converter. The layout of the transformer and the inductor is provided, so that the parasitic resistance of the winding in the magnetic core assembly is minimum. An auxiliary switch and an auxiliary winding are additionally arranged on the six-switch flying capacitor voltage reduction type conversion circuit, and the auxiliary switch and the auxiliary winding are used for providing enough energy for the output end when the input voltage is lower than four times of the output voltage. A switch layout is provided to reduce parasitic parameters and power losses of a transformer winding AC loop, and parasitic parameters and power losses on the switch bridge arm path.
