Description

Use inductor class to create an inductor object that you can add to an existing circuit.

Inductor representation

Creation

Syntax

lobj = inductor(lvalue)
lobj = inductor(lvalue,lname)

Description

lobj = inductor(lvalue) creates an inductor object, lobj, with an inductance of lvalue and default name, L. lvalue must be a real scalar.

example

lobj = inductor(lvalue,lname) creates an inductor object, lobj, with an inductance of lvalue and name lname. lname must be a character vector.

Properties

Inductance, specified as a real scalar in henries.

Example: 1e-9

Example: lobj.Inductance = 1e-9

Name of inductor object, specified as a character vector. Two elements in the same circuit cannot have the same name.

Example: 'cap'

Example: lobj.Name = 'indcutor1'

Names of the terminals of inductor object, specified as a cell vector These names are always p and n.

Example: {'p' 'n'}

Example: lobj.Terminals = {'p' 'n'}

Full path of the circuit to which the inductor object belongs, specified as character vector. This path appears only after the inductor is added to the circuit.

Note

"ParentPath" is only displayed after the capacitor has been added

into a circuit.

Parent nodes connected to inductor terminals, specified as a vector of integers. This property appears only after the inductor is added to a circuit.

Example: [1 2]

Example: lobj.ParentNodes = [1 2]

Note

"ParentNodes" are only displayed after the capacitor has been added

into a circuit.

Create an inductor object and extract the s-parameters of this inductor.

hL = inductor(3e-9,'L3nh');
hckt = circuit('example2');
add(hckt,[1 2],hL)
setports (hckt, [1 0],[2 0])
freq = linspace (1e3,2e3,100);
S = sparameters(hckt,freq);
disp(S)
  sparameters with properties:

      Impedance: 50
       NumPorts: 2
     Parameters: [2x2x100 double]
    Frequencies: [100x1 double]

Add an inductor to a circuit, display the parent path and parent nodes.

hL = inductor(3e-9,'L3n9');
hckt = circuit('example3');
add(hckt,[1 2],hL)
setports(hckt, [1 0],[2 0])
disp(hL)
  inductor: Inductor element

     Inductance: 3.0000e-09
           Name: 'L3n9'
      Terminals: {'p'  'n'}
    ParentNodes: [1 2]
     ParentPath: 'example3'
