FIG. 1 shows an example of the main circuit of a DC motor control device that automatically and variably controls the field amount of a DC motor using a thyristor chopper. In FIG. 1, the field winding of the DC motor is composed of a first field winding F1 and a second field winding F2 . By inserting the second field winding F2 into the freewheeling diode D F circuit in series with the child A, we can take advantage of the fact that the current in the freewheeling diode circuit changes as the conduction rate of the chopper CH changes. Accordingly, the amount of magnetic field of the DC motor is automatically and variably controlled. The current flowing through the freewheeling diode circuit is CH
Since the current is intermittent based on on/off control, a freewheel diode D A and a resistor R P are connected in parallel with the second field winding F 2 to smooth the current flowing through the second field winding F 2 . ing. In addition, the circuit in Figure 1 shows the case of an electric car that receives power from the overhead wire via the pantograph PG, so the reactor Lf is used to smooth the voltage and current on the power supply side.
A filter circuit consisting of a capacitor Cf and a capacitor Cf is provided.

Now, it is well known that the current controlled by such a chopper CH becomes a pulsating current, and the first field winding current I F1 in the circuit shown in FIG.
(equal to the armature current I M ) and the second field winding current I F2 are each pulsating currents as shown in FIG. Therefore, the first field winding F 1 and the second field winding
Considering that the field winding F 2 of is coupled via the excitation core, the pulsation of the second field winding I F2 is calculated as △I F2 . However, γ: Current flow rate of chopper (γ=T 1 /T) CH : Chopper control frequency ( CH = T 1 /T) L F1 : Inductance of first field winding F 1 L F2 : Second field Inductance of magnetic winding F 2 N F1 : Number of turns of first field winding F 1 N F2 : Number of turns of second field winding F 2 ΔI F1 : Number of turns of first field winding F 1 Pulsation component k: Coupling ratio between the first field winding F1 and the second field winding F2 .

が、この方法では制御装置の価格が高く、重量の
重いものになつてしまう欠点がある。 If the field current pulsation of a DC motor is large, the rectification of the motor will deteriorate, leading to damage to the commutator or brushes or flashover accidents, so the pulsation of the field current should be kept as small as possible. This is desirable. In order to reduce current ripples, a method of inserting a current smoothing reactor has been considered, but this method has the disadvantage that the control device is expensive and heavy.

FIG. 3 shows a circuit according to an embodiment of the present invention. In the circuit of FIG. 3, the first field winding in the circuit of FIG.
A third freewheeling diode D B in parallel with F 1
are connected in parallel. Due to the freewheel action of the diode D B , the current pulsation Δ9F1 of the first field winding current I F1 becomes extremely small as shown by the dotted line in FIG. 4A. As a result, the value of the pulsating component ΔI F1 of the first field winding current I F1 shown in the second term of equation (1) becomes small, and the pulsating component of the second field winding current I F2 decreases. △I F2 becomes small as shown in Figure 4 (b). 100KW for the vehicle mentioned above
When considering the electric motor, we found that the pulsation component △I F1 of the first field winding current I F1 was approximately 1/3 of that of the circuit in Figure 1 due to the freewheeling action of the diode D B , so the above (1 ) The value of the second term in the equation is 1 to 1.3 times the value of the first term, that is, the pulsation of the second field winding current I F2 △I F2 is approximately 50% of the circuit in Figure 1.
