Dr. Ali Shirsavar from Biricha Digital / OMICRON Lab in this video session explains how to make all the necessary calculations to show how we can use off-the-shelf transformers in power supply designs.
Configurable, off-the-shelf transformers have been available for many years. However, their use is not common and general consensus is that you need a custom transformer even for the simplest of designs.
A quick search on the internet shows that when it comes to off-the-shelf transformers, design information is very scarce, few guidelines are available and Application Notes do not show how to change and scale the specifications.
Wouldn’t it be great to be able to order your transformers from your favorite part supplier along with all your other components?
We will provide all of the necessary equations for scalable hand calculations first, but also provide a comprehensive spreadsheet with a multitude of possible combinations of turns ratios and parameters to enable extremely fast design of low power PSUs. The session concludes with a step-by-step design example of a Flyback converter.
