Magnetic Builder is a tool for user to create his/her own magnetic component by selecting different ferrite core, bobbin type and winding method. Engineering drawing will be automatically produced to reduce user work load.
All the transformer build can be saved and reused onto a power supply, as long as the winding number are matched.

choose how the wire is arranged if more than 1 layer is needed to complete the
winding in the “Multi-Layer Winding” box
Shared – wire will evenly shared in each layer
Tight – wire will be just tightly wind.
User can
choose how the creepage tape is placed in the “Creepage Position” box

detail information for making a professional transformer drawing.
User can fill in checking
parameter, e.g. DC resistance, Magnetizing Inductance and Leakage Inductance,
for IQC. Once the check box is clicked, the value between the corresponding
pins is enabled for inspection. Simulated value is recommended but user can
change the actual IQC specification by change wording in the corresponding text
box.
User can fill in the testing
details in the bottom of Transformer Drawing interface.
User press “Select Bobbin” at the top-right side and will
see the following page.
Click on
the picture to select bobbin type
User can change the number of
pins of bobbin there.
In “Generate
Drawing” page (section 7.8.44), user press “Add Fly Pins” at the top-right side and user
can see the following page.
User can
add or delete fly pins pressing corresponding button
After
