Transformer

Transformer with two ports

Modelica Standard Library

	Description
	The Transformer component models a two-winding transformer as a two-port with each port having self and mutual inductances.

	Equations
	$i_{1} = i_{p1} = - i_{n1}$ $i_{2} = i_{p2} = - i_{n2}$ $v_{1} = v_{p1} - v_{n1} = L_{1} \overset{&period;}{i_{1}} + M \overset{&period;}{i_{2}}$ $v_{2} = v_{p2} - v_{n2} = M \overset{&period;}{i_{2}} + L_{2} \overset{&period;}{i_{2}}$

Variables

Name	Units	Description	Modelica ID
$v1$	$V$	Voltage drop over the left port	v1
$v2$	$V$	Voltage drop over the right port	v2
$i1$	$A$	Current flowing from pos. to neg. pin of the left port	i1
$i2$	$A$	Current flowing from pos. to neg. pin of the right port	i2
