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 ...

Note: This article is based on the 2020 NEC. A transformer transfers electrical energy (power) from one system to another by induction, with no physical connection between the two systems (other than ...

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 ...

In switched-mode power supplies (SMPS), magnetic components, namely inductors and transformers, play critical roles. Much of the SMPS design process relies on component specifications and simulation ...

Designing flyback transformers for switch-mode power supplies involves many calculations. A spreadsheet can make short work of this otherwise-tedious task. When you develop flyback power supplies, ...
