Current limiting device for electronic controllers or actuator of loads with non-linear current-voltage characteristic curve

摘要

The device has a current limiting characteristic line (1) including non-linear characteristics with two different gradients that are not zero or infinite in sections. A shape of the current limiting characteristic line is approximate to a nonlinear shape of a load characteristic line (2). The current limiting characteristic line is shifted against the load characteristic line such that a voltage regulator supplies rated current of a load i.e. electric motor, with consideration of all circuit tolerances in all voltage ranges, where the load current is limited depending on a load voltage.
