wUBeta  = - (Stat_Volt_Input.qV_Component2 * T);  // 注意:这里T是4倍周期

wX = wUBeta;
wY = (wUBeta + wUAlpha) / 2;
wZ = (wUBeta - wUAlpha) / 2;

......

switch (bSector)
{
case SECTOR_1:
// 这里(T/8)是怎么来的,为啥不除以131072的????
hTimePhA = (T / 8) + ((((T + wX) -wZ) / 2) / 131072);
hTimePhB = hTimePhA + wZ / 131072;......

......

}

我不明白的就是上面hTimePhA = (T / 8) ...这行, 其实有2个问题, 如上面注释, 感觉T/8跟PWM中心对齐有关,但又不理解.
