Abstract:
An on-board current control device comprising:a processing unit outputting a current basic pulse width modulating signal by operating a current command value from engine controlling information and driving control information and outputting a current adjusting pulse width modulating signal from current adjusting information; a current regulator modulating the current basic pulse width modulating signal by the current adjusting pulse width modulating signal and generating a current command pulse width modulating signal; a smoothing filter removing a high frequency part of the current command pulse width modulating signal and converting to a current command signal; a comparator outputting a signal in response to a deviation obtained as a result of a comparison between the current command signal and a current feed-back signal; an output transistor controlling a current value applied to the load by the output from the comparator; and a current detecting means generating the current feed-back signal by detecting the current value applied to the load.
