25、损耗！如果不加续流二极管，当突然增大至 180或出发脉冲丢失时，由于电感储能不经变压器二次绕组释放，只是消耗在负载电阻上，会发生一个晶闸管导通而两个二极管轮流导通的情况，这使ud成为正弦半波，即半周期 ud为正弦，另外半周期为 ud 为零，其平均值保持稳定，相当于单相半波不可控整流电路时的波形，即为失控。所以必须加续流二极管，以免发生失控现象。方案二：单相桥式全控整流电路电路简图如下：图 4-2 单相桥式全控整流电路文档编码:CN1Y6J5F9M4 HM2K1D3I3N9 ZC6Q7T9S5M8文档编码:CN1Y6J5F9M4 HM2K1D3I3N9 ZC6Q7T9S5M8文档编码:CN1Y6

33、此种电路。方案四：单相全波可控整流电路：电路简图如下：图 4-4 单相全波可控整流电路此电路变压器是带中心抽头的，结构比较复杂，只要用 2 个可控器件，单相全波只用 2 个晶闸管，比单相全控桥少 2 个，因此少了一个管压降，相应地，门极驱动电路也少 2 个，但是晶闸管承受的最大电压是单相全控桥的2 倍。不存在直流磁化的问题，适用于输出低压的场合作电流脉冲大（电阻性负载时），且整流变压器二次绕组中存在直流分量,使铁心磁化，变压器不能充分利用。而单相全控式整流电路具有输出电流脉动小，功率因数高，变压器二次电流为两个等大反向的半波，没有直流磁化问题，变压器利用率高的优点。相同的负文档编码:CN1Y6

41、u 过零变负时，电感上的感应电动势使VT1、VT2继续导通，直到VT3、VT4被触发导通时，VT1、VT2承受反相电压而截止。输出电压的波形出现了负值部分。在电源电压2u 负半周期间，晶闸管 VT3、VT4承受正向电压，在 t时触发，VT3、VT4导通，VT1、VT2受反相电压截止，负载电流从VT1、VT2中换流至 VT3、VT4中在2t时，电压2u 过零，VT3、VT4因电感中的感应电动势一直导通，直到下个周期VT1、VT2导通时，VT3、VT4因加反向电压才截止。值得注意的是，只有当时2，负载电流di才连续，当时2，负载电流不连续，而且输出电压的平均值均接近零，因此这种电路控制角的移相范围
