　　中文：　　扼要电压哺养到变压器两种渠道(TR1,TR2)通过与二极管由tyristorsTYR1-TRY6替换使用的中间点的开关S1.A全波整流器.直接电压由电容器C过滤并且哺养对基本的contro单位古芝的输入Uin(参见fig.2).基本的二次绕组的Each一半有三个部分.tyristorsTYR1-TYR6的换向是由CU(产品T1-T6)控制的：首先,当产品电压增加from0时,tyristorsTYR1andTYR2是操作(哺养由二次绕组的第一个部分),并且直接电压有最小的价值.增加产品电压tyristorsTYR3和TYR4接通,并且直接电压也增加,因为他们由基本的二次绕组的第二个部分供应.(TyristorsTYR1和TYR2自动地关掉,因为他们的负极电压高于阳极一.)在更高的产品电压tyristorsTYR5和TYR6被接通,并且直接电压达到它最大的价值.当产品电压是越来越少的时,tyristors按相反顺序关掉.tyristor控制被描述的方法保证在调控的晶体管Q的最小的电压下落和最小的功率损失和各自最大的效率. 　　The产品电压是由它从产品UREF为此接受被稳定的参考电压通过开关S2,产品电压可能是开关"on"和"off"的电位器P1.调控的. 　　你是学电学的吗?
