| 摘 要： | 采用空间向量原理，从空间电荷向量端点轨迹逼近于国出发，推导出ＰＷＭ脉冲模式的算法，同时采用８０９７微处理器实现这种脉冲模式和对逆变器进行控制。由实验波形看出，在较低频时逆变器的输出电流为三相对称的近似的正弦波电流，消除了低频时有害的寄生脉动转矩。

| Abstract: | A PWM pulse pattern algorithm is derived from the space charge vector end whose trace is approximating a circle, on the principle of space vector. This pulse pattern is realized and the inverter controlledthrough 8097 microprocessor. The test waveforms show that output current of the inverter displaya 3-phase,ymmetric and approximating sine under lower frequentes, thus eliminate the harmful peasitic pulsating torquet lower frequencies. |
