PSIM User Manual 2-19

Images:

In the images, p refers to primary, s refers to secondary, and t refers to tertiary.

The winding with the larger dot is the primary winding (or the first primary winding for

the 2-primary-2-secondary-winding transformer (TF_1F_4W)). For the multiple winding

transformers, the sequence of the windings is from the top to the bottom.

For the transformers with 2 or 3 windings, the attributes are as follows.

Attributes:

All the resistances and inductances are referred to the primary side.

For the transformers with more than 1 primary winding or more than 3 secondary wind￾ings, the attributes are as follows.

Parameters Description
