The forward converter does appear similar to the flyback transformer, but it is actually very different. The forward converter transfers its energy instantly (transformer action) unlike the flyback which stores and then releases that stored…

Most everything we use of convenience and need these days is electrically powered. Most often we have access to a source of voltage at one, or maybe two particular values. Unfortunately in many cases the…

In transformer design, there is an equation most of us are familiar with. This equation is known as the “transformer design equation”. This equation is applicable for inputs that are of most any voltage. The…

One flavor of a high frequency switching transformer is known as a push-pull transformer. A push–pull transformer is a DC-to-DC switching transformer; it is often used to change a power supply’s DC voltage. These power…

In the spirit of the season, CET Technology would like to wish everyone Happy Holidays and a Happy New Year with our Custom Magnetics Song! Enjoy! Twelve Days of CET Christmas On the first day…

Predicting the final temperature of a part is not always an easy thing to do. It becomes a complex task for complex parts. We’re going to predict this final temperature for something simple, like an…

In order to design a current sense transformer you need to determine the DCR of the SEC, the inductance of the SEC, the SEC wire area/gauge to use, the magnetic area of the core, the…

Transformer voltage regulation for no load and full load voltages. So you’ve chosen a bobbin, wire, PRI turns, etc… now you want to spec an output voltage under LOADED conditions and determine the SEC turns…
