DEVICE FOR SWITCHED RELUCTANCE DRIVE CONTROL Russian patent published in 2016 - IPC H02P6/08 H02P25/08 H02P27/08 

FIELD: electricity.

SUBSTANCE: control device envisages sensorless operating principle for switched reluctance motor with reswitching of the stator phase windings against sign of the preset level reaching by calculated instantaneous flux linkage. The preset value of magnetisation complies with the predefined and recorded curve of magnetisation. Correction of active phase resistance at heating is carried out against result of phase switching. The moment of completion of phase switching period is detected by current control comparator. Synchronisation for operation of current integrator and flux linkage integrator, dividing unit, temporary data storage unit and controlled switch is provided by three time delay units delaying propagation of control signals.

EFFECT: higher reliability of the device.
