From the point of view of message groups, the first important thing to note is that the constant MQPMO_LOGICAL_ORDER is added to the put message options. 从消息组的角度而言,要注意的第一个重要方面是向put消息选项添加了约束MQPMOLOGICALORDER。
To achieve PFC, this mode divides the logical control into two parts, then it determines the prescribed maximum inductor current and the minimum inductor current respectively by constant turn-on time technology and the average inductor current signal. 将电路的逻辑控制分为两个相对独立的部分,分别利用恒导通时间控制技术和平均电感电流信号来确定电感电流的上限和下限,即可实现PFC。
