description: The purpose of this work is to increase energy efficiency and research ways tocontrol electric drives. The following tasks are analyzed in the work: 1. Methods of regulating the speed of blood pressure; 2. Calculation of the control system with the initial engine data. 3. Converting devices for variable frequency drives. 4. Methods for assessing the energy characteristics of an electric drive with athyristor and semiconductor frequency converter. 5. Calculation of energy characteristics.The paper analyzes research, the basic methods for controlling the speed ofrotation (scalar control, vector control, direct control of the torque), calculation anddetermination of the parameters of equivalent circuits, methods for evaluating theefficiency and power consumed from the network, evaluating the loss methods inpower switches, in a bridge inverter are provided voltage and in stand-alone voltageinverters with pulse-width modulation. The energy characteristics of electric driveswere also calculated:with thyristor regulation; with frequency converter (FC) with autonomous voltage inverter (AVI) and controlled rectifier; with FC with AVI andscalar PWM; with FC with AVI and vector PWM; with direct torque control.
