Soft magnetic materials (materials that can easily be magnetized) come in many forms. For switchmode power supply flyback transformers and chokes, we would consider gapped ferrites, Iron powder, ...

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, ...

While switch-mode power supplies operate at frequencies well above the range of human hearing, they can produce audible noise under certain load conditions. Potential sources of audible noise can vary ...

Oftentimes the biggest obstacle indesigning an isolated dc/dc converteris the transformer design, a prospectthat sometimes discourages designersfrom undertaking an otherwisestraightforward design task ...

ABB began developing drytype transformers for medium voltage applications in the 1970s, recognizing that oilfree technologies help transformers comply with the highest safety standards for people, ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...
