Power Supply Tutorial Welcome! To ensure the appropriate level of high availability and reliability for powering critical telecom applications, service providers must consider a combination of the ...

Here are 4 simple 12V power supply circuits with output voltages around 12V. First power supply circuit is built with BD139, one zener diode and a few passive components. Each of the schematic is very ...

Is my power supply OK? What about my microprocessor? What if something goes wrong? Simulations show what happens if DC ...

Here is an ideal Power Supply Unit for trouble shooting the circuit boards. It gives Five and Nine volt regulated DC from a Rechargeable battery. It is portable and handy and can also functions as a ...

Remember that power-factor correction circuits are not perfect, sometimes only providing a power factor close to 1 when the power supply is at or near rated full load.

Switch-mode power supplies (SMPS) continue to replace linear-regulator types in a host of applications. As the need for more efficient electronics accelerates and as a result of their size, weight ...

But for circuits where weight, volume, or cost are a major concern, a transformer may be omitted in the circuit design in favor of some sort of transformerless power supply.

Well if you're looking for some information on Power Supplies, Hardware Secrets has 10 pages of PSU goodness. No, this isn't any kind of PSU roundup. In their latest article you'll find ...

Modern integrated circuits are increasingly vulnerable to power supply noise and the ensuing induced jitter, phenomena that can significantly impair circuit reliability and performance.
