When connecting two equal-turn windings in parallel on the same core, the

When connecting two equal windings in series, the combined

The amount of current flowing through the series combination that causes the same temperature rise as the parallel combination is calculated as follows:

rearranged in the form

Where:

and it is assumed that:

With two equal windings in parallel, Isat is the same as that of one winding. With two equal windings in series, the number of turns is doubled, which doubles

When wires are bifilar wound, the isolation between them will be quite small, and not routinely tested. Therefore, it is recommended that sufficient testing of samples be performed to verify a safe isolation voltage for the application.
