For example: sine pulse width modulation technology (SPWM), Make the frequency conversion technology to realize the popularization. In the variable pressure variable frequency speed regulation system, should meanwhile adjust the speed of the stator voltage and frequency of the power supply, in this case, the basic characteristics of parallel machine movement, slip the same. Using the technology of the frequency converter performance of SPWM more perfect, can get the more widely. 目 录
