在高开关频率和低占空比转换时，占空比的导通时间被抑制到很短的周期。三电平转换器将导通时间延长到两倍。通过伪斜坡控制器（PRC）和自动涟漪消除（ARC）拓扑结构，飞跨电容被平衡到50%的输入电压，占空比精度提高了11倍，输出电压纹波提高了3 mV。
In high switching frequency and low duty conversion, the on-time in duty cycle is restrained to brief period. The three-level converter extends the on-time to two times larger. By Pseudo-Ramp Controller (PRC) and Auto-Ripple Cancellation (ARC) Topology, flying capacitors are balanced to 50% input voltage with the accuracy of duty cycle improves 11 times and 3mV output voltage ripple.
