摘要
本文提出了VVVF的谐波问题,对几种不同控制方式的变频装置,例180°导电型逆变器,PWM脉冲宽度控制型式的逆变器的谐波问题进行了分析。并对交流变频调速装置在使用中出现的谐波影响作了估计。提醒人们在低频运行时可能出现的问题。最后,介绍了高性能的矢量变换控制(transvec-tor control)技术。
The presence of harmonic is put forward by analysing some variable frequency devices in different cortrol mode such as 180°turn-on converter and PWM pulse width-modulated converter.
Harmonic impact on motors while VVVF devices being driven is estimated and problems occuring under low frequency running of the motor are cited.
Finally, high performance transvector control technique is introduced.
