Bobbin Setting

Click the button "Select Bobbin" at the top-right side of the Generate Drawing page and you will see the Select Bobbin Type page.



At this page, you can select the bobbin type by clicking the bobbin type and deltermin the number of poins at the combo box as shown above.

Besides even number of pin numbers, odd number of pins are also available. E.g. 5(2+3) Pins mean 2 pins at left side and 3 pins at right side.

Monte Carlo Analysis for MOSFET is now available. Print or export schematics easily.
Magnetic Builder -- Estimate Loss Page

In Magnetic Builder Modules, user can go to the advanced page of Magnetic builder by pressing "Advance" button. Click the "Estimate Loss" button will redirect user to estimate loss page as shown below.

User can simulate the loss and other performance of the transformer by applying an ac square wave with programmable positive duty cycle Don, peak positive voltage Vpos, switching frequency fs and dc bias current Idc. Other winding can also program a positive and negative loading current which will be conducted corresponding to the dot sign and in ac square wave. Corresponding performance curve is shown at the bottom of the page.

User can find the inductance of an inductor or transformer under dc current bias. Inductances shown in the Estimate Loss page will be changed accordingly with the dc bias current Idc. A corresponding curve can be found at the bottom of the page too.
