Abstract
Energy recovery of various types is an urgent task in the development of control systems for electromechanical devices. rational and careful use of energy resources. The purpose of this work is to analyze four-quadrant asynchronous electric drives with vector frequency-current control systems and autonomous voltage inverters with sinusoidal pulsewidth modulation based on IGBT modules. The design algorithm is considered and the results of modeling of such energy recovery systems are given. The proposed control system of the recovery device can be used as an integral part of a specialized controlled electric drive for escalator stations of the subway, electric transport and other electromechanical systems in order to save energy consumed.
