Introduction If it is necessary to control the dc motors only in the power running mode, the mixed bridge rectifiers are used widely and their dc voltage can be DC series motors are used extensively for ac electric railway because of their good speed control characteristics. DC voltage and dc current to drive dc series motors a r e supplied from a single-phase rectifier on vehicles and controlled by an on-load tap changer. Due to the increase of thyristor capacity, however, there are many cases in recent years where the dc voltage and dc current a r e controlled by thyristors. Needless to say, thyristor-controlled dc voltage and dc current a r e distorted greatly and have bad effects on power apparatus (such as feeding transformer, autotransformer, frequency converter, reactive power supply equipment, etc.), protective devices (such as distance relay, fault detector, etc.), train speed and train position control systems. In addition, the distorted dc voltage and dc current interfere electromagnetically with communication lines. On
