| 摘 要： | 提出用数字信号处理器芯片TMS320F28335作为功率驱动器主控芯片,实现矢量空间解耦的六相空间矢量脉宽调制控制方法.以双Y相移30°六相永磁同步电机为研究对象,推导出实现矢量空间解耦控制过程中12个扇区内ePWM硬件模块控制规律.试验结果表明,用TMS320F28335作为主控芯片,易于实现复杂的矢量空间解耦的多相电机驱动控制,且输出的多路PWM波形、滤波后的相电压波形和线电压波形符合双Y相移30°的永磁同步电机驱动要求,有效抑制电压谐波空间的5、7次谐波,达到抑制谐波电流的目的.

| Abstract: | A chip of DSP TMS320F28335 was proposed as a power driver control chip to realize the vector space decomposition control of 6-phase space vector pulse width modulation(SVPWM).A control law of ePWM hardware module was derived within 12 sectors considering the features of ePWM hardware,when the research object was a dual three-phase permanent-magnet synchronous motor(DTPMSM).The experimental results showed that the TMS320F28335,which was used as the control chip,was suitable to implement the complex process o... |
