A new state-of-the-art Variable Frequency Transformer (VFT), a key component in a 138-kV electric interconnection between Laredo and Mexico was dedicated May 18, at the Laredo VFT substation. Texas ...

This variable power supply is using 7805, 7809, 7812 or 7815 voltage regulators, where the last 2 digits represents the maximum output voltage of the IC. This circuit offers excellent ripple rejection ...

This 3V to 24 volt variable-regulated power supply can be adjusted from 3 to 25 volts and is current limited to 2 amps as shown, but may be increased to 3 amps or more by selecting a smaller current ...

• LVDTs produce a linear electrical output directly proportional to the position of a movable ferrous core of nickel-iron alloy. • Two secondary windings in the LVDT produce identical output voltages ...

The demand for higher efficiency and smaller packages has been the driving force behind advances in switch-mode power-conversion topologies including buck, boost, flyback, forward converters, and ...

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 ...

There are myriad operational and safety challenges when loading a transformer near its end of life, from the impact of overload situations or network faults on aged assets to the increased system ...

According to Research Intelo, the global power transformers market size reached USD 32.7 billion in 2024, driven by robust investments in grid modernization and renewable energy integration worldwide.
