摘要

采用多相电机和PWM变换器的系统存在较大的脉动。采用多级变流器和多相并联电抗器时，减小绕组螺距会使其增大，减小绕组螺距会使其减小。使用多级变换器可以显著降低直流链路中电容器的电流负载。

Dependence of Current Pulsations of Multi-Phase Electrical Machine on Reduction of Winding Pitch and Scheme of Semiconductor Converter

There are sizeable pulsations in system with multi-phase electrical machines and PWM converters. They are increased under reduction winding pitch and decreased under using of multi-stage and multi-level converters and multi-phase paralleling reactors. Use of multi-stage convert-ers allows appreciably to decrease current load of capacitors in DC link.
