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 excitation current, the % error of the CT and the desired output voltage for a given input current. Let’s start…
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…
