置に関するものである。Description: TECHNICAL FIELD The present invention relates to a weak field injection control device for an electric vehicle that performs field control by additively exciting the main field of a series winding motor from another power source. .

No. 05) is the main circuit in the embodiment.

る。The operation at the time of power running will be described with this main circuit. First, when the main circuit contactor 7 is turned on, a current starts to flow in the main circuit.
At this time, the weak field contactor 8 is not turned on, and the field control device 6 is not operating. Therefore, the main circuit current flows through the armature 1, the field winding 2, the bypass diode 10 and the main resistor 5 as shown in FIG. As the speed increases, the resistances of the resistors 5 are sequentially short-circuited, and when all the resistances are short-circuited, the whole field is changed to the weak field control.

調整される。When the field weak contactor 8 is turned on and the field controller 6 is operated at the same time, the armature current I A changes to the field current I F as shown in FIG. 2b.
And the shunt current I S, and the output current I EX of the field controller 6
The shunt rate of the field current I F and the shunt current I S , that is, the weak field susceptibility is adjusted by appropriately controlling the phase control of the thyristor.
界磁制御装置６の電源には補助電源装置（図示せず）を
使用する。An auxiliary power supply device (not shown) is used as a power supply for the field control device 6.
なおこの場合界磁制御装置６を動作させない場合の分流

抗値を選択しておく。In this case, the resistance value of the induction shunt 3 is selected so that the shunt ratio when the field control device 6 is not operated is smaller than the weakest field susceptibility.

り、電機子電流が減少してしまう。(Problems to be Solved by the Invention) In the control when the weak field contactor 8 is turned on to start the operation of the field control device 6, generally, when the weak field contactor 8 is turned on, the thyristor of the field control device 6 is closed. It is usual to fix the phase of to minimum or maximum. However, if the phase of the thyristor is fixed to the minimum, the output current I EX of the field controller 6 does not flow at the moment when the weak field contactor 8 is turned on, so the field susceptibility becomes equal to or lower than the weakest field, and the electric field is reduced. Inrush current flows through the child 1. Further, when the phase of the thyristor is fixed to the maximum, the output current I EX of the field controller 6 is applied to the field weak contactor 8 when the field weak contactor 8 is closed.
0, the weak field contactor 8 and the induction shunt 3 flow in the closed loop, the field is strengthened, and the induced voltage of the armature 1 is increased to decrease the armature current.

同様の強め界磁状態となってしまう。In addition, it is naturally conceivable to fix the phase between the maximum and minimum in order to mitigate the above-mentioned drawbacks, but in this case as well, the notch of the main controller is kept in the full field operation state to increase the speed. Then, the armature current becomes small, and if the weak field contactor 8 is turned on in such a state, the same strong field state as that described above will be obtained.

点があった。In other words, if the phase angle of the thyristor is fixed to a certain value, it is necessary to provide a dead zone in order to prevent problems such as hunting. However, if the dead zone is provided, the control response will be hindered and a problem will occur. That is, the conventional device has a drawback in that the rush current flows or the current suddenly decreases, so that the riding comfort of the vehicle deteriorates.

弱界磁投入制御装置を提供することを目的とする。SUMMARY OF THE INVENTION It is an object of the present invention to provide a weak field closing control device for an electric vehicle that can eliminate these drawbacks.

行できるようにする。(Means for Solving Problems) Since the optimum value of the phase control angle of the thyristor of the field control device changes depending on the state when the weak field contactor 8 is turned on, in the present invention, the auxiliary power supply device changes the phase control angle to the thyristor of the field control device. By setting the phase control angle to be always in an active state (operable state) without providing a dead zone and fixing it to a constant value, a command can be directly issued when the weak magnetic field contactor 8 is turned on. Is given so that the optimum phase control angle can be instantaneously changed.

ことを特徴とする。That is, using the DC series-wound motor according to the present invention, the field winding control is performed by adding and exciting the series winding field winding from another power source, and the electric vehicle control device using the thyristor phase control method in this field control device. In the weak field closing control device, the field control device is not operated in the entire field region during power running, the phase control angle (command) to the field control device is activated, and the field control device is not operating. It is characterized in that a phase control angle (command) is applied to the thyristor when the weak field is applied to activate the field control device.

It is also possible to improve the disadvantage that the riding comfort of the vehicle is deteriorated by eliminating the problem that the electric current suddenly decreases.
