clarke3 - Clarke (3 phase to cartesian) transform
loadrt clarke3 [count=N|names=name1[,name2...]] |
The Clarke transform can be used to translate a vector quantity from a three phase system (three components 120 degrees apart) to a two phase Cartesian system (plus a homopolar component if the three phases don’t sum to zero).
clarke3 implements the general case of the transform, using all three phases. If the three phases are known to sum to zero, see clarke2 for a simpler version.
