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 air coil inductor. The mathematics found can “loosely” be applied to more complicated parts but certainly the approach can be…
Push Pull Switching Transformer Design
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 supplies are known as switched-mode-power-supplies (SMPS). Older, linear power supplies often used low frequency, heavy silicon steel type transformers to…
