forestage

The energy from the Boost operational mode transfers directly through forestage flyback can improve efficiency of converter.

通过前级工作在反激、Boost状态中的直接能量传输提高变换器的效率。

The forestage of the fusion model completes target presort and its post-stage is used to multi-period uncertainty inference and the whole set distribution of probability.

该推理模型前级采用神经网络并行子网，用于目标的预分类，后级采用证据理论用于多周期的不确定性推理和概率的全局分配。

The forestage PFC circuit has three operational modes: non-conduction mode, flyback operational mode, Boost operational mode.

前级PFC有三种工作状态，分别是：不导通状态、反激工作状态、Boost工作状态。
