【 摘 要 】

The article describes the influence of the voltages non-sinusoidal form of the supplying three-phase network to the rectified voltage's quality of the multipulse rectifier with a ring connection of the valve arm. The created mathematical model makes it possible to determine the shape of the rectifier's rectified voltage taking into account the asymmetry and non-sinusoidal voltage of the supply network. The results of calculations using a mathematical model are verified by way of physical model. The aim of research is to find out the most stable rectification scheme in case of three-phase network power supply of rectifier.
