Linear inductor in electrical systems

Electrical Elements

The Inductor block models a linear inductor, described with the following equation:

$$V=L\frac{dI}{dt}$$

where

`I` | Current |

`V` | Voltage |

`L` | Inductance |

`t` | Time |

The **Series resistance** and **Parallel
conductance** parameters represent small parasitic effects.
The series resistance can be used to represent the DC winding resistance
or the resistance due to the skin effect. Simulation of some circuits
may require the presence of a small parallel conductance. For more
information, see Modeling Best Practices.

Connections + and – are conserving electrical ports corresponding
to the positive and negative terminals of the inductor, respectively.
The current is positive if it flows from positive to negative, and
the voltage across the inductor is equal to the difference between
the voltage at the positive and the negative terminal, *V*(+)
– *V*(–).

**Inductance**Inductance, in henries. The default value is

`1`

µH.**Series resistance**Represents small parasitic effects. The series resistance can be used to represent the DC winding resistance. The default value is

`0`

.**Parallel conductance**Represents small parasitic effects. The parallel conductance across the inductor can be used to model insulation conductance. Simulation of some circuits may require the presence of a small parallel conductance. The default value is

`1e-9`

1/Ω.

Use the **Variables** tab to set the priority
and initial target values for the block variables prior to simulation.
For more information, see Set Priority and Initial Target for Block Variables.

The block has the following ports:

`+`

Electrical conserving port associated with the inductor positive terminal.

`-`

Electrical conserving port associated with the inductor negative terminal.
