The urgency of the work is due to the need to develop a multi-motor frequency-controlled electric drive for cord clipping lines. The study of the construction of energy-efficient multi-motor drives, with the help of reversible frequency converters, which can reduce the total installed power of the multi-motor drive of the cord line. Justification of the choice of the most suitable design, based on the use in the inverter current circuit of lockable gates such as GTO or IGBT and polar damping capacitors as part of protection against possible increases in switching overvoltage.
