摘　　要：介绍了一种应用自对相及相位自适应触发器的高精度低纹波晶闸管直流稳流电源 ,它的主电路采用两组三相桥式全控整流桥并联获得 12相脉波 ,其稳流精度很高而纹波含量较低 ,文中详细介绍了其工作原理 ,并给出了在 30 0 0A/ 2 0 0V晶闸管直流电源中的实际运行效果。A kind of high precision and low ripple ware thyristor DC constant power supplies using self correct phase and self adaptation phase variable trigger is introduced in this paper. Because of its main circuit of two three phase all controlled rectifier bridge in parallel, so the 12 phase result ripple wave is got. The performance of constant current precision is very high and ripple wave is also very low. Not only the work mechanism is discussed, but also the real result in 3000A/200V thyristor DC Power Supples is given.
