9、sforms the three phases of the mains into six phases. The six phases are rectified in a 12-pulse semi-conductor full bridge. The rectifier is made up of six thyristor/ diode modules. 3 of each are placed on a DC/AC module and the 3 remaining one are placed on a cooling element below the DC/AC module
10、. The combination of the 12-pulse rectifier, the 12-pulse transformer and the input filter choke means that there is hardly no harmonic feed back into the mains (i.e. no mains pollution/distortion). (12脉冲变压器将3相输入电源变为6相。6相通过12-脉二极管全桥整流。整流器由6个半导体闸流管/二极管模块组成，其中3个安装在DC/AC模型上，3个安装在DC/AC模型下的散热器上。12-脉冲整流器、
11、12-脉冲变压器及输入滤波电感的混合意味几乎没有谐波返回到输入回路.（也就是没有输入电路/畸变）。 )The 12-pulse rectifier also provides a soft start by gradually increasing the firing angle of the thyristors. This way, the inrush current caused by the low-pass filters capacitor is limited to a value inferior to the converters nominal current. Dur
12、ing operation, the thyristors are fully turned on and the rectifier bridge is acting as an un-regulated 6-phase rectifier bridge.(12-脉冲整流器也通过逐步打开二极管的导通角实现软启动。这样来讲，通过低通滤波的电容器使输入电流被限制为低于静变电源正常电流值。在操作过程中，二极管的导通角全部打开，整流器桥是不需要调整的6相整流器一样工作。 ), the safe choice .,DC/AC module(DC/AC 模块),The 12-pulse rectifie
13、r system is characterised by an almost sinusoidal line current and a power factor better than 0,96. This means less stress on the main supply network and distribution transformers.(12-脉冲整流器系统的特征为正弦曲线电流，功率因数大于0.96。这意味着减少对输入网络和变压器输出的影响。 )The DC Filter smoothes the pulsating DC voltage from the 12-puls
14、e rectifier to a level which does not cause any significant voltage modulation at the output.At ohmic inductive load, the filters capacitor battery supplies the reactive part of the current which means that the converters apparent output power (kVA) might be bigger than the consumed power. (DC滤波减少DC
15、电压的波动，从12-脉冲整流器输出,不会影响任何明显输出电压模块的水平。在阻性负载中，滤波器的电容储能提供了部分由于感抗引起的电流，意味着静变电源外部视在功率（kVA）可能大于消耗功率。 )Based on the un-regulated DC voltage, the converters inverter part generates a 400 Hz voltage with adjustable amplitude. (由于DC电压不需要调整，静变电源的逆变器产生400Hz可调幅电压。 ), the safe choice .,Processor (程序器模块),Processor
