It is frequently advantageous to employ a transformer-less power supply solution to provide the required supply to low-power circuits. In fact, it is possible to convert the input AC voltage into DC ...

When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

According to Texas Instruments, its latest high-density isolated DC-DC modules with integrated transformers shrink isolated bias power supplies in automotive and industrial systems by close to 90%.

The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...

For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

About two decades ago there was a quiet revolution in electronics which went unnoticed by many, but which overturned a hundred years of accepted practice. You’d have noticed it if you had a mobile ...

Engineers from the Electricity Company of Ghana (ECG) have successfully installed a high-capacity transformer at the production side of the Anwomaso Bulk Supply Point to meet the current and future ...
