Description

This model represents an ideal electrical inductance. The element has a preferred current out causality. The corresponding constitutive equations then contain an integration. The element can also have the non-preferred voltage out causality. The constitutive equations then contain a derivation. The port p of the inductor model has separate high and low terminals. The equations are:

 

p.i = p_high.i = p_low.i;

p.u = p_high.u - p_low.u;

 

current out causality (preferred):

 

p.i = (1/L)int(p.u);

 

voltage out causality:

 

p.u = L * ddt(p.i);

Interface

Ports

Description

p_high, p_low

Both terminals of the Electric port p.

Causality

 

preferred current out

An voltage out causality results in a derivative constitutive equation.

Parameters

 

L

Inductance [H]

Initial Values

 

p.i_initial

The initial flux in the inductor.
