A solid-state transformer (SST) is an AC-AC converter, sometimes called a power electronics transformer (PET), that replaces ...

Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

Let's look at key formulas that are the building blocks for the transfer of electricity: real and reactive power transfer formulas and their basics. The power triangle represents an essential building ...

Solid state transformers (SSTs) represent a transformative shift in power electronics, replacing conventional electromagnetic transformers with semiconductor-based devices that offer enhanced ...

Power transformers are often the main source of common-mode noise in isolated switching power converters. Why? Because inside the transformer, the windings on the primary and secondary sides of the ...

I’m sure many readers would question why anyone would want to perform a relatively expensive insulation power factor test on an inexpensive transformer. Typically, if any testing is done, it will be ...
