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.
