HAL Component — CLARKE2V2

INSTANTIABLE COMPONENTS — General

All instantiable components can be loaded in two manners

Using loadrt with or without count= | names= parameters as per legacy components
Using newinst, which names the instance and allows further parameters and arguments
primarily pincount= which can set the number of pins created for that instance (where applicable)

NAME

clarke2v2 — Two input version of Clarke transform

SYNOPSIS

clarke2v2

USAGE SYNOPSIS

loadrt clarke2v2
OR
newinst clarke2v2 <newinstname> [ pincount=N | iprefix=prefix ] [instanceparamX=X | argX=X ]

( args in [ ] denote possible args and parameters, may not be used in all components )

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. .P \fBclarke2\fR 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. \fBclarke2\fR 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.
