Abstract
According to the six-switch flying capacitor voltage buck-type conversion circuit and the four-switch flying capacitor voltage buck-type conversion circuit applied to the intermediate bus converter, further optimization is provided. On one hand, a power conversion device is provided, the voltage peak of the switch is absorbed by optimizing the clamping circuit and the layout thereof, the voltage stress of the switch is reduced, no extra loss is generated, and the conversion efficiency of the power conversion device is improved. On the other hand, by optimizing the current sampling circuit, the monitoring and control performance related to the current is optimized, and the size of the power conversion device is reduced.
