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": [
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“.
