Title: Automatic resistor stepping up device for electric car
Inventor: ISHIKAWA YOSHITOSHI
IPC: B60L15/22
Filed: 1979-07-02
Abstract: PURPOSE: To prevent the current variation which could cause the flashover in a motor, by adding current limit control to the stepping conditions in the case of automatic stepping, and providing a judging circuit to determine whether a current is flowed or not for a specified time length through a resistor for each notch curve.  
     CONSTITUTION: A resistor switching device 120 is connected to one side of a resistor group 110. Said device 120 has a function to connect the resistor of a resistor group whose value is larger or smaller than the resistor which is now connected complying with the external command. A current limiting value detector 130 and a timer 140 are connected to the device 120. The detector 130 detects the current flowing through the resistor which is connected to the device 120. When the detected current decreases below a specified value, the detector sends out a signal. While, the timer 140 begins to measure the time length corresponding to the time the current is flowing, during the time the drift of the resistance value is not generated, by inputting the signal which indicates the resistor connected by the device 120. The timer 140 sends out a signal when time is up.
