我搞SVPWM电机调速，看资料。我看到计算电压矢量扇区号，计算出扇区号以后，应该再做什么呢？
程序里根据N=4*C+2*B+A，计算出扇区后，再做什么呢？程序里我只看懂计算扇区的部分。其他看不懂。
比如下面一段是什么意思？
if (Sector==0) // Sector 0: this is special case for (Ualpha,Ubeta) = (0,0)
{
v->Ta = _IQ(0.5);
v->Tb = _IQ(0.5);
v->Tc = _IQ(0.5);
}
if (Sector==1) // Sector 1: t1=Z and t2=Y (abc ---> Tb,Ta,Tc)
{
t1 = Vc;
t2 = Vb;
v->Tb = _IQmpy(_IQ(0.5),(_IQ(1)-t1-t2)); // tbon = (1-t1-t2)/2
v->Ta = v->Tb+t1; // taon = tbon+t1
v->Tc = v->Ta+t2; // tcon = taon+t2
}
else if (Sector==2) // Sector 2: t1=Y and t2=-X (abc ---> Ta,Tc,Tb)
{
t1 = Vb;
t2 = -Va;
v->Ta = _IQmpy(_IQ(0.5),(_IQ(1)-t1-t2)); // taon = (1-t1-t2)/2
