Rules and information of use
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The dictionary values containing the different parameters of the core and
the windings that compose the choke. You must not change the main structure of
the dictionary. The dictionary has many primary keys, including
``"Number of Windings"``, ``"Layer"``, and ``"Layer Type"``, that have
dictionaries as values. The keys of these dictionaries are secondary keys
of the dictionary values, such as ``"1"``, ``"2"``, ``"3"``, ``"4"``, and
``"Simple"``.
You must not modify the primary or secondary keys. You can modify only their values.
You must not change the data types for these keys. For the dictionaries from
``"Number of Windings"`` through ``"Wire Section"``, values must be Boolean. Only
one value per dictionary can be ``"True"``. If all values are ``True``, only the first one
remains set to ``True``. If all values are ``False``, the first value is chosen as the
correct one by default. For the dictionaries from ``"Core"`` through ``"Inner Winding"``,
values must be strings, floats, or integers.
Descriptions follow for primary keys:
- ``"Number of Windings"``: Number of windings around the core
- ``"Layer"``: Number of layers of all windings
- ``"Layer Type"``: Whether layers of a winding are linked to each other
- ``"Similar Layer"``: Whether layers of a winding have the same number of turns and same spacing between turns
- ``"Mode"``: When there are only two windows, whether they are in common or differential mode
- ``"Wire Section"``: Type of wire section and number of segments
- ``"Core"``: Design of the core
- ``"Outer Winding"``: Design of the first layer or outer layer of a winding and the common parameters for all layers
- ``"Mid Winding"``: Turns and turns spacing ("Coil Pit") for the second or mid layer if it is necessary
- ``"Inner Winding"``: Turns and turns spacing ("Coil Pit") for the third or inner layer if it is necessary
- ``"Occupation(%)"``: An informative parameter that is useless to modify
The following parameter values work. You can modify them if you want.

Convert dictionary to JSON file
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Covert a dictionary to a JSON file. PyAEDT methods ask for the path of the
JSON file as an argument. You can convert a dictionary to a JSON file.

.. GENERATED FROM PYTHON SOURCE LINES 127-134
Verify parameters of JSON file
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Verify parameters of the JSON file. The ``check_choke_values`` method takes
the JSON file path as an argument and does the following:
- Checks if the JSON file is correctly written (as explained in the rules)
- Checks inequations on windings parameters to avoid having unintended intersections
