基于空间电压矢量法的风机变频调速系统的设计

The design of frequency conversion timing system based on the method of space electric voltage vector for fan

为了消除风机调速中的谐波分量 ,提出了一种新型的风机调速系统。该系统主电路采用三电平PWM变频器 ,以 16位单片机 80 98为核心组成数字控制系统 ,并采用空间电压矢量法的控制方法。该系统用于风机 。

For the sake of eliminating the harmonic ,this paper brings forward a new timing system for fan.The device uses three-level PWM transducer as the main electric circuit of the system, 16 bits CPU 8098 as the the core of the digital control system. It adopts the method of space electric voltage vector as the control measure.It may gain the better timing characteristic when being applied to the fan.
