Many surge protectors incorporate surge protection—and now with lots of handheld devices that charge at low voltages, they’re more important than ever.

In this episode of the PSDcast, we're chatting with Helix Semiconductors about the idea of transformer-less AC-DC Converters. We're all familiar with transformers and their role in ac-dc conversion circuits, but lately, their disadvantages have become a lot more blatant ... Click on the PS...

Circular Mils Q : For transformers the current carrying capability of wire is often listed in "circular mils" What is a circular mil, and how do I relate it to the real world? Thanks a lotA: The unit "circular mils" is a strange unit. It is a measure of area--the area of a circ...
Power distribu- tion systems, with associated transformers and distribution impedances, can produce voltage drops or surges with other loads on the power network; these loads can circulate harmonic currents and exciting resonances between inductive and capacitive compo- nents. Industrial power supplies ...
I actually think the bigger constraint is going to be transformers, which are already constrained. And you have a two year lead time today. And I hear anecdotes of hyperscalers going ahead and buying up big stocks of those to be ready to build whatever is in their plans....

The decision variable of this market-based mechanism is the new power supplied by external suppliers, which is represented by PSP_new(VPP,t). 4.2. HV/MV Power Transformer Pro-Rata Mechanism In this mechanism, the DSO imposes limits to the HV/MV power transformers which defines the maximum ...
Equation (17) preserves the bounded operation of tapping points of the transformers. The voltage profile is kept within the permissible operating limits as in Equation (18). Equation (19) preserves the transmission lines within the secure operation by limiting the power flow in the acceptable ...
