Model of core losses

Modelica Standard Library

	Description
	The Core component models core losses.

	Equations
	$i = {\begin{array}{c} 0 & P_{ref} \leq 0 \\ \frac{v P_{ref}}{V_{ref}^{2}} & otherwise \end{array}$ $v = v_{p} - v_{n}$ $i = i_{p} = - i_{n}$ $lossPower = v i$

Variables

Name	Units	Description	Modelica ID
$v$	$V$	Voltage drop between the two pins	v
$i$	$A$	Current flowing from pin p to pin n	i
$lossPower$	$W$	Loss power leaving component via heat port	lossPower

Connections

Name	Description	Modelica ID
$p$	Positive pin	p
$n$	Negative pin	n
$heatPort$	Conditional heat port	heatPort

Parameters
