Abstract

Purpose. Development of original models of voltage inverters adapted to control a single-phase asynchronous motor with the subsequent prospect of creating automatic systems for improving the energy efficiency of household mechanisms, as well as developing educational complexes for studying the operation of frequency converters to form skills for their repair and tuning.Methodology. The provisions of the theory of electric machines, methods of synthesis of digital control systems, methods and methods of modeling in CAD electronic laboratory of the company NATIONAL INSTRUMENTS of the Multisim component, methods of circuit design were used for conducting research. Findings. Models of pulse distributors were developed and built for the cases of power supply of single-phase asynchronous motors with bridge inverters of separate and individual starting and working windings, half-bridge inverters with a bipolar power source and a three-phase inverter with control according to a 180-degree control diagram. Time diagrams of visual confirmation of the system's performance according to the declared principles have been obtained. Originality. A number of original switch diagrams of the power section of the models of impulse distributors of autonomous voltage inverters are proposed, taking into account the phase shift and the duration of the switching pauses of the switching arms of the power unit to avoid emergency modes, recommendations are given on the levels of generation frequencies that are fed to the input of the combinational circuit, the prospect of using this system as part of a single-phase asynchronous electric drive with the possibility of energy-efficient control is shown.Practical value. The proposed original model solutions for autonomous voltage inverters, which are adapted to work together with a single-phase IM, can be useful for developers of converter technology and become visual material for their use in the educational process for training specialists in specialty 141 "Electric power engineering, electrical engineering and electromechanics".
