摘要

本文分析了基于4个不连续同步调制逆变器的六相非对称电机驱动的调制过程。研究表明，基于直流电压对逆变器开关频率的控制的灵活PWM策略可以提高系统性能，并保证在调节范围内电压波形的对称性。仿真验证了具有基本控制模式的系统的运行。

Six-phase motor drive with variable switching frequencies and voltage synchronization of inverters

In this paper, modulation processes have been analyzed in six-phase asymmetrical motor drive on the base of four inverters with discontinuous synchronous modulation. It has been shown, that flexible PWM strategy based on control of switching frequencies of inverters as function of dc voltages allows to improve system performance and to insure voltage waveform symmetries during adjustment range. Simulations validate operation of systems with basic control modes.
