Saturable inductor and saturable transformer share the same magnetizing inductance parameters
How to specify the magnetizing inductance parameters of a saturable inductor/transformer in the Schematic Editor?
The saturable inductor/transformer block uses a table-defined magnetizing inductance.
This file has to be in a specific format which is described below.
What is the format of the saturable magnetizing inductance parameters file ?
The saturable magnetizing inductance parameters are described in a JSON format. The following parameters must appear in the file.
Parameter (JSON key) | Value type | Unit | Description | Example |
---|---|---|---|---|
magnetizingFluxBreakpoints | double[] | Wb | Core magnetizing flux | "magnetizingFluxBreakpoints": [ |
currentValues | double[] | A | Current through the magnetizing branch | "currentValues": [ |
The examples provided above, when combined in a valid JSON format, would appear as follows:
{ "magnetizingFluxBreakpoints": [ 0.0, 0.0000129, 0.00002, 0.0000227, 0.0000236, 0.0000239 ], "currentValues": [ 0.0, 0.64, 1.28, 1.92, 2.56, 3.2 ] }
Parameter constraints
The following constraints applies the saturation characteristic:
where
is the magnetizing flux, and
is the magnetizing current.
Additionally, the number of elements of the array “magnetizingFluxBreakpoints“ shall be the same of “currentValues“.
