HAL Component — CLARKE3

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

clarke3 — Clarke (3 phase to cartesian) transform

SYNOPSIS

clarke3

USAGE SYNOPSIS

loadrt clarke3
OR
newinst clarke3 <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 (plus a homopolar component if the three phases don’t sum to zero). .P \fBclarke3\fR implements the general case of the transform, using all three phases. If the three phases are known to sum to zero, see \fBclarke2\fR for a simpler version.
