Title:
CURRENT CONTROL CIRCUIT
Document Type and Number:
Japanese Patent JP3235331
Kind Code:
B2
Abstract:
PURPOSE: To make possible high-speed response to both the sudden change of setting of a current command value and disturbance and remove the steady- state deviation from the current command value of the quantity of AC.
CONSTITUTION: This relates to a current control circuit which gets the output voltage command value of a voltage type of power converter by adding the output of a current adjuster and a compensation signal, being equipped with a current adjuster 12 which feeds back the output current of a voltage-type power converter, based on the deviation between the command value and the detection value, and a feed forward compensating circuit 15 which operates the compensation signal, based on the output current value, according to the load impedance. This is equipped with a primary delay element 17, where an output current command value i* is inputted, or an acceleration and deceleration computing element, and inputs the deviation between the output current command value i* and the output current detection value l through these into the current adjuster 12.
