在采用降压开关功率开关转换器降低正输入电压的同时,通常还需要一个额外的低功率负输出电压。
When we use low-dropout switching power switching converter to reduce positive input voltage, we usually need an extra low - power negative output voltage.
如果输入的电压是正三伏,那么输出的电压便是负六伏。
If the input voltage is plus three, it comes out as minus six.
每一级正相和负 相信号输出端分别与各输出缓冲电路的正相和负相输入端相连。
The input ends of positive phase and negative phase of the first time-delay unit are respectively connected with the output ends of positive phase and negative phase of the last time-delay unit.
