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 ...

For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...

As modern society takes uninterrupted electricity supply for granted, electrical utility providers are increasingly measured by the reliability of the infrastructure used to deliver power to consumers ...

When designing an offline flyback power supply, integrating the IC with the other components can be overwhelming. Integrating the transformer properly is more than finding the turns-ratio to match ...

Note: All Code references are based on the 2014 NEC. The NEC has separate sections for transformer feeder protection and transformer protection. Article 240 lists requirements for transformer feeder ...

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 ...

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 ...

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

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 ...
