NAME

       clarke2 - Two input version of Clarke transform

SYNOPSIS

       loadrt clarke2 [count=N|names=name1[,name2...]]

DESCRIPTION

       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.

       clarke2 implements a special case of the Clarke transform, which  only  needs  two  of  the  three  input
       phases.   In a three wire three phase system, the sum of the three phase currents or voltages must always
       be zero.  As a result only two of the three are needed to  completely  define  the  current  or  voltage.
       clarke2  assumes  that  the  sum  is  zero,  so  it  only  uses phases A and B of the input.  Since the H
       (homopolar) output will always be zero in this case, it is not generated.
