CIRCUIT OF LIMITING LOAD RUSH CURRENT IN DIRECT CURRENT INPUT-PART HAVING INDUCTIVE LOAD

摘要

An embodiment of the present invention relates to a circuit structure of limiting inrush current from a DC power supply stage having an inductive load. Provided is the circuit structure of limiting inrush current comprising: a current control unit using a poly switch to supply current below a certain criteria; a feedback control unit for driving a transistor if the load voltage becomes higher than a reference voltage by applying the supplied current; and a circuit unit using the signal of the transistor to receive the limited current.
