Saturable magnetizing inductance parameters file

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

Parameter (JSON key)	Value type	Unit	Description	Example
magnetizingFluxBreakpoints	double[]	Wb	Core magnetizing flux	"magnetizingFluxBreakpoints": [ 0.0, 0.0000129, 0.00002, 0.0000227, 0.0000236, 0.0000239 ],
currentValues	double[]	A	Current through the magnetizing branch	"currentValues": [ 0.0, 0.64, 1.28, 1.92, 2.56, 3.2 ]

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“.
