Using a flyback topology to generate a high voltage is a common approach. The voltage can charge a capacitor for a high-energy pulse. Such an approach is used in defibrillator capacitors, photoflash ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

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 ...

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, ...

Here are the steps required to select the transformer and how to design the circuit needed to meet the end use in a manner that prevents transformer saturation Average current-mode control (CMC) ...
