Title:
CURRENT CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/059152
Kind Code:
A1
Abstract:
According to the present invention, a current acquisition unit (57) acquires an excitation current. A steady control unit (59) maintains an average value of the excitation current to be around a command current. A target determination unit (62) determines whether a target current is changed at the time of a steady control. A full-on control unit (63) puts a solenoid (43) in a full-on state at a first timing which arrives in a control shift period, after the target current has been changed to an ascending side. A full-on determination unit (64) determines whether the excitation current is equal to or greater than a full-on threshold. A first full-off control unit (65) puts the solenoid (43) in a full-off state at a first timing which arrives in an energization switching period, after the excitation current is equal to or greater than the full-on threshold. A first full-off determination unit (66) determines whether the excitation current is equal to or smaller than a full-off threshold. A control shift unit (69) shifts to a steady control at a first timing which arrives in the control shift period, after the excitation current is equal to smaller than the full-off threshold.
