Input
Input
Output voltage conversion is comprised of dq-to-αβ coordinate axis conversion and 2-phase-to-3-phase
The dq-to-αβ coordinate axis conversion calculates Vα and Vβ from Vd, Vq in SIN and COS.
The 2-phase-to-3-phase conversion performs segmentation by using Vα and Vβ and performs space
For the 2-phase-to-3-phase conversion, either 2-phase modulation or 3-phase modulation can be
