DEVICE FOR DIRECT TORQUE CONTROL OF ASYNCHRONOUS MOTOR BASED ON THREE-PHASE THREE-LEVEL INDEPENDENT INVERTER NPC Russian patent published in 2024 - IPC H02P21/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering and can be used to control a three-phase three-level voltage inverter, the control system of which uses a method of direct control of the motor torque. Device for direct torque control of an asynchronous motor based on a three-phase three-level self-contained inverter NPC by installing a stator flux linkage setting unit, a seven-position relay torque controller and a three-command vector selection unit allows to increase accuracy and speed of reaction of the asynchronous motor torque control system.

EFFECT: increased accuracy and speed of reaction of the asynchronous motor torque control system.
