The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

Inductors and transformers serve key roles in switch-mode power supplies. Ensuring they perform as expected requires thorough in-circuit measurements performed under operating conditions. Here’s what ...

Every non-battery-powered electronic device requires converting offline ac power to some dc voltage for powering electronics. Nowadays, efficient conversion of electrical power is becoming an ...

Abstract: In this paper a new approach for optimization of high frequency transformer design is presented. The presented design method is based on a restatement of the traditional transformer design ...

Abstract: A new formula aimed at calculating ohmic losses in switch-mode power supply (SMPS) transformers is presented. It is based on intensive two-dimensional (2-D) finite element method (FEM) ...
