The programme through the transformer transformer, through the rectifier circuit filter circuit which will be AC into DC, and the adoption of the regulation by regulators more stable voltage, input voltage regulator when it can only be fixed when the voltage difference within the scope of regulation of the output voltage, and therefore out of voltage difference in the scope of automatic Diaodang, it is through the two comparator output voltage and the reference voltage comparison, and through the counter counting function control relay controller The input to determine the size of the output voltage at which the scope, and then automatically Diaodang.

该方案是通过变压器变压，再经过整流电路、滤波电路进而将交流电变为直流电，在通过稳压器的稳压得到较稳定的电压，由于稳压器当输入电压固定时只能在它的电压差范围内调节输出电压，、所以要在调出电压差的范围时自动调档，这是通过两个比较器将输出电压和基准电压进行比较，再通过计数器的计数功能控制继电器控制器的输入情况来判断输出电压的大小在哪个范围，然后进行自动调档。
