When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

Analyzing a power system's stability usually begins with a look at the open-loop Bode plot of a buck or flyback converter's power stage. From this plot, the designer extracts phase and gain data for ...

Conservation Voltage Reduction (CVR) is a power-saving innovation. A review of BGE’s deployment of Conservation Voltage Reduction technology on a large scale involves cutting customers’ electricity ...

Power system stability and security assessment is a critical field that ensures modern electrical grids operate reliably amid increasing demands, renewable integration and evolving cyber threats. This ...

To ensure the stability of dc-dc converters, most power-system designers adhere to the common rule that input source impedance should be small compared to the converter's input impedance. Not all ...

A farmer is watering an alfalfa field 24 hours a day using a 3-phase 100-hp electric motor and adjustable speed drive (ASD). The farmer checks on his field to find the water not flowing and the pump ...

In the electronic field, an oscillator is a circuit capable of producing a self-sustained sinusoidal signal. In a lot of configurations, cranking up the oscillator involves the noise level inherent to ...

Read an introduction to this series in Part 1, and Part 2, which covers noise. This is the third and final part in a series which discusses how to properly test a power supply to ensure it will work ...

High-voltage direct current (HVDC) technology offers several advantages compared to alternating current transmission systems. For example, it allows more efficient bulk power transfer over long ...
