The features of the application of the balancing transformers with artificial switching as regulated power sources of the process plants are considered. The proposed approach makes it possible to convert AC to DC to supply the load and simultaneously generate reactive power of a capacitive nature, which is aimed at meeting the current Russian and foreign standards for electromagnetic compatibility of the consumer with the supply network. The characteristics obtained as a result of computer simulation in the MATLAB Simulink environment and its SimPowerSystems application confirmed the main positive features of compensation converters. It is shown that the main advantage of controlled compensation converters is the possibility of creating a frequency-controlled asynchronous electric drive with separate frequency and voltage control, which will significantly improve the energy characteristics of an asynchronous motor by reducing losses, increasing the service life of insulation, and significantly improving electromagnetic compatibility.
