摘要： The d.c. power collected from an overhead contact line (L) is converted into a three-phase alternating current by the action of a three-phase inverter (INV) of variable voltage and frequency. The three-phase alternating current is commonly supplied to a plurality of driving three-phase induction motors (IM1...IM4). The output voltage of the inverter (INV) is so constructed as to hold the motor current at a constant level. The output frequency of the inverter (INV) is determined by adding or subtracting the present value of a slip frequency (f5) to or from the frequency signal (f1) which correponds to the running speed of an electric car. Here, the frequency signal corresponding to the running speed of the electric car is determined by memorizing first and second pulse generators (PG1...PG4), attached to the induction motors (IM1...IM4) to indicate the maximum and the minimum during the coasting run of the electric car, and by adding or subtracting the slip frequency (f5) to and from the output of the first pulse generator (e.g. PG1) during the power run and the output of the second pulse generator (e.g. PG4) during the regeneratively braked run.

摘要： Power is supplied from a DC electric car line (1) through an L-C filter (3) to a PWM inverter (4). The three-phase AC output from the inverter (4) is applied to an induction motor (5) for driving an electric car. The output frequency of the inverter (4) is determined by adding or subtracting the slip frequency to or from the speed frequency of car. On the other hand, the output voltage of the inverter (4) is controlled by PWM so that the deviation as a result of comparing the current command to motor and the actual motor current is reduced to zero. In this case, an electric oscillation of current flowing from the DC electric car line (1) to the filter (3) is detected by a CT (13) with an air gap, and the electric oscillation is suppressed by adjusting the output voltage or frequency of the inverter.

摘要： The two secondary windings (N 21 , N 22 ) of a transformer the primary winding (N,) of which is connected to an AC power supply (P s ) are each provided with a controlled rectifying circuit (R f1 , R f2 ). The DC sides of the rectifying circuits (R f1 , R f2 ) are connected in series to supply power to DC motors (M, M 1 -M 6 ). One of the secondary windings (N 21 , N 22 ) is detachably connected with a capacitor bank (CLC). The capacity of the capacitor bank (CLC) is selected so that the power factor of the converter can be improved to a satisfactory value when the two rectifying circuits (R f1 , R f2 ) are both controlled to produce output voltages. The capacitor bank (CLC) becomes connected in response to the fact that the current in the primary winding (N,) of a transformer (T r ) has arrived at a predetermined value.
