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 ...

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 ...

SAN JOSE, Calif.--(BUSINESS WIRE)--Power Integrations (Nasdaq: POWI), the leader in gate-driver technology for medium- and high-voltage inverter applications, today announced a range of galvanically ...

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 ...

Today, ac adapters are used to supply dc power to a variety of systems, from laptop computers to many computer peripherals. These power supply designs must consider not just functionality requirements ...

Here, Rich Miron, Applications Engineer at Digi-Key Electronics explores the operation of switch mode power supplies and explores make Vs. buy decision process for power supplies. Miron also ...
