关于28335电机控制的电流采样问题,多谢了

Other Parts Discussed in Thread: CONTROLSUITE

在TI controlSUITE中28335的HVPM_Sensorless_2833x 例程里面 关于AD有 :

#ifdef DSP2833x_DEVICE_H

clarke1.As=((AdcMirror.ADCRESULT1)*0.00024414-offsetA)*2*0.909; // Phase A curr.

clarke1.Bs=((AdcMirror.ADCRESULT2)*0.00024414-offsetB)*2*0.909; // Phase B curr.

 #endif                 // ((ADCmeas(q12)/2^12)-offset)*2*(3.0/3.3)  

clarke1.As和clarke1.Bs进行了标幺处理了吗, 为什么我通过DA 在示波器和CCS 观测窗口观测的时候,结果值很多时候超过1了, 还有为什么会除以3.3呢?
