Information × Registration Number 0218U006609, 0117U000094 , R & D reports Title Emergency operation diagnostic systems and control systems of the frequency converter included in the frequency-controlled electric drive popup.stage_title Head Melnykov Viacheslav, Registration Date 25-06-2018 Organization Kremenchuk Mykhaylo Ostrogradskiy State University popup.description2 Heve been developed are Methods for monitoring emergency operation modes of a frequency converter as part of a frequency-controlled electric drive , based on the introduction of additional compensating signals into closed circuits of regulating the stator current of the motor. It is shown that the use of the proposed control system makes it possible to compensate for the variable component of the active power consumed from the network, the output power of the inverter by 70%. At the same time, the proposed system makes it possible to reduce the heat losses of the most loaded phases by an average of 51%, which extends the life of the insulation of the stator windings of the induction motor. Also, heat losses in the most loaded diodes of the input bridge rectifier are reduced by 80%, in transistors of the autonomous voltage inverter by 42%, which increases the lifetime of the frequency converter.
