Description: 变频驱动主要使用的驱动波形主要有SPWM和SVPWM两种。SPWM原理简单、实现容易,是现在使用最广的一种变频驱动波形。但其有一个致命的弱点是其电源利用率不高（只有86％）、谐波成分大。因此,在新近开发的产品中其应用逐渐被性能优异的SVPWM所取代。SVPWM是一种电压利用率、低谐波成分的变频驱动波形,还有开关次数少、功率管功耗小等特点。同时,SVPWM还能很好的结合矢量控制算法、以最大限度的发挥设备的性能。因此被越来越多的变频设备所采用。-The main use of variable frequency drive drive waveform SPWM and SVPWM are mainly two. SPWM principle of simple, easy, is now the most widely used as a variable frequency drive waveform. But there is a fatal weakness is its power utilization is not high (only 86), large harmonic components. Therefore, in the newly developed products in its application performance is gradually replaced by SVPWM. SVPWM is a voltage utilization, low-harmonic component waveform of variable frequency drive, there are fewer switches, power control features such as power consumption small. At the same time, SVPWM also a very good combination of vector control algorithm to maximize the performance of the play equipment. Therefore increasingly being used by the inverter equipment.
