摘要： PURPOSE:To omit a chopper exclusive for the case of the titled braking operation by effectively utilizing a semiconductor converter for regulating field currents not only on power-running operation but also on the regenerative braking operation. CONSTITUTION:A regenerative braking main resistor 17 is connected to the armature group 3 of a first motor group, and a regenerative braking main resistor 19 is connected to the armature group 5 of a second group. On the other hand, the semiconductor converters 21, 22 for a magnetic field system are each connected to the field winding group 4 of the first motor group and the field winding group 6 of the second motor group. When the resistance values of the regenerative braking main resistors 17, 19 are regulated by short-circuit switches 18, 20, the semiconductor converters 21, 22 for regulating field currents are controlled just before the short-circuit switches 18, 20 are operated so that the generating torque of the motors or the variation of armature currents after the short-circuit switches 18, 20 are operated is kept within a prescribed range, and field currents are regulated previously.

Likewise each converter commutation is done in turn and at the phasial angle of the finished commutation of the last converter 22 the communication of all converters 16-22 will finish.

摘要： PURPOSE:To reduce power consumption with a simple and inexpensive means by connecting a pair of series circuits, either of which consists of a capacitor and a diode and is connected with a discharge element having a slow discharge characteristic in parallel, in parallel so that the polarities of diodes are opposite to each other. CONSTITUTION:Voltage polarity is reversed from negative to positive at the time t2' in one operation periode T the thyristor 10 is turned off at t0 and on at t5, the diode 16 conducts and the capacitor 18 is charged three times at t1, t2 and t3 because the polarity of interelectrode voltage is negative. Since the discharge resistance 22 which has a slow discharge characteristic such that a discharge completes at t5 is connected, the variation of charge voltage of the capacitor 18 is suppressed in a small range. When the polarity of interelectrode voltage of the thyristor is reversed from negative to positive, the diode 12, capacitor 14 and discharge resistance 20 operate like said elements. Thus power consumption can remarkably be reduced by means of the resistances 20, 22.
