CURRENT-LIMITING DEVICE FOR ELECTRONIC CONTROLLER OR ACTUATOR FOR LOAD HAVING NONLINEAR CURRENT-VOLTAGE CHARACTERISTICS

摘要

PPROBLEM TO BE SOLVED: To provide a current-limiting device with the conformity with electric current limitation to motor characteristics has been improved. PSOLUTION: An electronic current-limiting device is provided in a voltage controller or a current controller for loads, having nonlinear current-voltage characteristics (2). A load current is restricted, depending on a load voltage, and a current-limiting line (1) features a nonlinear behavior, having at least two different slopes (excluding zero and infinity) into a partition shape.
