The mains voltage is fed to the transformers of both channels(TR1,TR2)through the switch S1.A fullwave rectifier with middle point in which the diodes are replaced by tyristors TYR1-TRY6 is used.The direct voltage is filtered by the capacitor C and fed to the input Uin of the base contro unit CU(see fig.2).
Each half of the base secondary winding has three sections.The commutation of the tyristors TYR1-TYR6 is controlled by CU(outputs T1-T6):at the beginning,when the output voltage increases from0,the tyristors TYR1 andTYR2 are operating(fed by the first sections of the secondary winding)and the direct voltage has a minimal value.With the increasing of the output voltage tyristors TYR3 and TYR4 are switched on and the direct voltage also increase,because they are supplied by the second sections of the base secondary winding.(Tyristors TYR1 and TYR2 switch off automatically because their cathode voltage is higher than the anode one.)At much higher output voltage the tyristors TYR5

电源电压输入变压器的两个通道（ TR1 ， TR2 ）通过开关S1.A全整流器中点，其中二极管取代tyristors TYR1 - TRY6是采用直接过滤的电压是由电容器C和喂养输入Uin的基础控制单元铜（见2 ） 。
每半个基地中学绕组有三个sections.The减刑的tyristors TYR1 - TYR6是由铜（产出表＃ t1 - 3.2 ） ：在年初，当输出电压增加from0的tyristors TYR1 andTYR2作业（助长了第一部分中学绕组）和直接电压最低value.With的增加，输出电压tyristors TYR3和TYR4的开关和直流电压也会增加，因为他们所提供的第二部分中学的基础清盘。 （ Tyristors TYR1和TYR2自动关掉，因为他们的阴极电压高于阳极之一。 ）在更高的输出电压的tyristors TYR5和TYR6的开关和直流电压达到其最大value.When输出电压下降的tyristors开关关闭在逆order.The描述方法tyristor控制确保最低限度的电压下降的调节晶体管Q和分别功率损耗最小和最大的效率。
该输出电压的调节的电位P1.For为此目的，收到了稳定的参考电压从输出系统联合通过开关s2中，其中输出电压可开关“开”和“关闭” 。
