Inductor
Inductance coil.
Description
The Inductor block models a linear inductance coil described by the following equation:
Where:
-
- voltage;
-
- inductance;
-
- current;
-
- time.
The Series resistance and Parallel conductance parameters represent small parasitic effects. Series resistance can be used to represent the ohmic resistance of a winding or the resistance caused by the skin effect. Some circuit modelling may require a small parallel conductance.
The + and - ports correspond to the positive and negative leads of the inductance coil, respectively. Current is positive if it flows from positive to negative and the voltage across the coil is equal to the potential difference across the positive and negative leads .
Ports
+ - positive
electricity
Electrical port, represents the positive terminal of the coil.
- is the negative
electricity
Electrical port, represents the positive terminal of the coil.
Parameters
Inductance - inductance of the coil
1e-6 Gn (by default) | positive | scalar
