These days, homeowners are clamoring for pendants that hang from the ceiling, moody undercabinet lighting, recessed lighting and outdoor path lights that illuminate the edge of the front walk. Of ...
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 ...
While troubleshooting the power supply of a 1970s Centurion system, [Usagi Electrics] came across a fascinating feature of these units: the ferroresonant, or constant voltage transformer (CVT). The ...
Cincinnati, Ohio — Ferroresonant transformers from Foster Transformer provide a stable power output (typically ±3%) for input voltages that vary as much as ±15%. The standard square wave ...
Tap changers are devices that can increase or decrease the output secondary voltage by changing the turn ratio of primary or secondary winding. A tap changer is usually installed on a high voltage ...
A new technical paper titled “Evaluation and Perspective of Analog Low-Dropout Voltage Regulators: A Review” was published by researchers at Universiti Tunku Abdul Rahman, University of Malaya, Asia ...
Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...
In the definition above, we would correctly diagnose something as a short when a path connects between two points of differential voltage, such as common and hot on a 24V transformer, without first ...
Power supply circuits come in the form of voltage step-up (boost) or the more common step-down (buck) DC/DC converter. Many of today’s applications require multiple voltage rails to drive a variety of ...
