Abstract

PURPOSE: To conduct constant voltage control without offset in a chopper controller for an electric motor vehicle by providing a low priority circuit at the output side of a comparator amplifier for producing a current flow rate instruction as an output.
CONSTITUTION: A stop notch pattern generator 20 receives 1 to 4 notch instructions 16 to 19 and produces voltage pattern 21 corresponding to the respective notches. The voltage pattern 21 is applied through a notch limiter 28 to a comparator amplifier 27 and low priority circuit 21. The output from a loading unit 22 is applied through a drive current limiting pattern generator 23 to a comparator amplifier 27. The signal from a motor current detector 25 is applied also to the amplifier 27. The output 30' from the amplifier 27 and notch pattern voltage 21 are applied to a low priority circuit 31, which thereupon produces a current flow rate instruction 30.
