Where,a was the high eight of calculation results and b is
low eight of the calculation results. Meanwhile, a was also
the current vector in the sector, and b represented the electric
Angle in this sector.
The following is to deduce each of the fundamental
voltage vector action time in a period.
According to the Uref and Angle θ calculated two
nonzero basic vector equivalent action time, T4 and T6 said,
specific as follows:
