CONTROL AND/OR ADJUSTMENT OF THREE-PHASE ELECTRIC ENERGY CONVERTER FOR ASYNCHRONOUS MACHINE OPERATION CONTROL Russian patent published in 2012 - IPC H02P21/12 H02P21/13 H02P27/06 H02P21/08 H02M5/451 

FIELD: electricity.

SUBSTANCE: control and/or adjustment device for control of operation of an asynchronous machine (K) with power supplied from a three-phase electric energy converter (G) contains a control and/or adjustment structure including the stator flow controller (R) and a pulse sequence generator (P) for generation of pulse signals based on average values; the stator flow controller (R) output is connected to the pulse sequence generator (P) input so that the pulse sequence generator (P) generates pulse signals depending on the control action produced by the stator flow controller (R); the stator flow controller (R) is designed so that to produce such control action depending on the set value of the asynchronous machine (K) stator flow and on the set value of the asynchronous machine (K) torque; the stator flow controller (R) has an aperiodic adjustment characteristics.

EFFECT: technical and economic performance improvement.
