This LED constant-current PRM (power-regulator-module)-regulator demonstration board aims at LED applications, including street and stadium lighting, high-end projectors, active-outdoor advertising, ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more.

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

When you think of wind farms, images of majestic towers with huge spinning blades spanning the horizon probably come to mind. Designers are not immune to this impulse, as their primary focus is on the ...

Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...
