(1) 3-phase-to-2-phase conversion
(2) αβ-to-dq coordinate conversion
conversion.
Output VETMPREG3 α-axis current
Output
Input current conversion is comprised of 3-phase-to-2-phase conversion and αβ-to-dq coordinate axis
The 3-phase-to-2-phase conversion calculates Iα and Iβ from la, lb and lc.
The αβ-to-dq coordinate axis conversion calculates ld and lq from Iα, Iβ, VESINM and VECOSM.
