单片机数字触发电路

晶闸管的导通是可控的。当它的阳极上加有正向电压时，在其触发极上加上适当的触发脉冲就能导通。针对晶闸管阳极上电压的相位变化，在恰当的时刻提供准确的触发脉冲，这种方法称为变流技术上的同步(也叫定相)。应用MCS-51(96)单片机作触发电路，可省去同步变压器和复杂的接法变换等，操作简单、准确可靠，还可在每个周波进行一次校对，控制精度较高。

Single a Machine Hair Electricity Road of Excellent Turn to Establish To Account

The thyristor is a controller device. Electricity passes thyough the thyristor,if the positive of the thyristor is connected to a postitive voltage and the trigger terminal of the thyristor gets pulse. It is called as the synchronous or locating phase of the converter technigue that synchronous signaling outputted by the trigger circuit is located accurately with changing the voltage phase on the positive of the thyristor.Applicution single chip micromputer as trigger circuit called has great creclibitity and it can be callated every weck the precision of controlling can be very high.
