摘　　要：在简单介绍级联式变频器的基础上,对多载波控制算法和阶梯波控制算法进行了分析。提出了一种新型优化控制算法,综合了上述两种控制算法的优点,能够实现低输出谐波含量和低开关损耗,且易于VVVF控制。通过Matlab软件对该算法进行了建模仿真,仿真结果表明该算法是可行性的。The cells cascaded inverter is introduced simply. Then the arithmetic of multicarrier control and stair waveform control is analyzed. A novel optimized arithmetic is proposed, which has both the advantages of multicarrier arithmetic and stair waveform arithmetic. The harmonic and switching lose can be reduced by this method. And VVVF control is easy to realize as well. This arithmetic is simulated by Matlb software. The results show that this arithmetic is feasible.
