Electric Drive with Common Rectifier and Individual Inverters for Asynchronous Electric Motors of Woodworking Line

Abstract

A frequency Converter of a woodworking line with a set of Autonomous voltage inverters connected to a common rectifier with an output LC filter is considered. The capacitance of the capacitor is formed from parallel connected capacitors at the input of all inverters. Autonomous voltage inverters work independently from each other on individual induction motors. The result of the use of such a frequency Converter is the improvement of the power supply system and the electric drive system of the woodworking line. First of all, the power supply system of inverters is improved at deviations and voltage fluctuations in the network. In addition, there is a rational redistribution of generator braking energy through a common link of constant voltage between the engines and reduce energy consumption from the network. The study of physical processes on the simulation model of the electric drive.
