Abstract

PURPOSE:To obtain a controller which has fast response of reducing an armature current by separately providing a step control system of an armature side output voltage and a control system of a field rate step. CONSTITUTION:A field side step controller 2 outputs a step of indicating a full field and stops until an armature side output voltage step controller 1 indicates the armature side output voltage maximum step. When the controller 1 outputs a step of instructing the maximum armature side output voltage, the controller 2 starts advancing the stage in the direction of weakening the field. When an overcurrent of an armature current is detected due to an abrupt rise of a trolley wire voltage during the weak field operation, a comand for advancing the step in reverse direction is applied to the controllers 1 and 2. When the step of the armature side is advanced in reverse direction, the response of reducing the armature current can be accelerated.

関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a control device for an electric vehicle, and more particularly to a control device for an electric vehicle that controls an armature side output voltage and a field rate in a stepwise manner.

点があった。Conventional electric vehicle control devices that control the armature output voltage and field rate in steps, as shown in Figure 1, continuously control the armature output voltage and field rate using the same step command system. However, with this method, if there is an unexpected change in the overhead line voltage during power running, if the field rate advances to the step that indicates the lowest value, the field rate will decrease as overcurrent will flow to the armature side. Control is performed by advancing the steps backwards in the direction of increasing the voltage, and after passing the step where the field becomes full, the steps are advanced in the direction of decreasing the armature side output voltage to reduce the overcurrent of the motor. . This method has the disadvantage that a quick response cannot be achieved due to a delay in field control during the progression of the step in which the field rate command value changes.

。The present invention provides a method for controlling the armature current due to an unexpected change in overhead line voltage when using a control device that controls the output voltage and field rate on the armature side in steps when controlling the field winding of a DC motor by separately excitation. In order to prevent deterioration of motor commutation due to sudden surges, we have separate step control systems for the armature side output voltage and field rate step control systems, and when an unexpected overhead line voltage or overcurrent is detected, both step control systems are controlled in the opposite direction. This allows for a quick response by commanding the next step.

を絞シ込む応答は速くなる。When the armature-side output voltage step control device 1 outputs a step that instructs the maximum armature-side output voltage, the field-side step control device 2 causes the field to be weakened. When an overcurrent in the child current is detected, a command is given to the armature side step control device and the field side step control device to advance the step in the opposite direction. By advancing the steps on the armature side in the opposite direction, the response to narrow down the spot current becomes faster.
