Distribution transformers must adhere to NEC and NFPA 70 standards, with specific requirements for overcurrent protection, ...

When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

One of the most dangerous locations in a power distribution system with regard to incident energy is that first panelboard on the secondary of a transformer. With some thought in your design — even if ...

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 ...

THE POWER SOURCES MANUFACTURERS ASSOCIATION (PSMA) is celebrating its twentieth anniversary by offering hardcopy reprints of a classic text on transformer design for less than a student would have ...

As a senior transformer consulting engineer at Doble Engineering Co., Dom Corsi has had the opportunity to inspect transformer factories around the world. He has witnessed the manufacturing of both ...

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) ...

Custom-designed transformers got a bad reputation a decade or two ago. One of the knocks against them was a lack of repeatability. It could be tough to get replacements that worked like the originals ...

Magnetic components, particularly transformers operating at high frequencies and voltages, are intrinsically influenced by parasitic capacitance. This unintended capacitance between conductive ...
