The circuit drawn pertains to a regular industrial UPS (Uninterruptible Power Supply), which shows how the batteries take control during an outage in electrical supply or variation beyond the normal ...

Power management plays a major role in virtually every electronic system because it controls, regulates, and distributes dc power throughout the system. Therefore, the dc power management subsystem ...

If the power source is a listed Class 2 transformer or listed Class 2 power supply — or it’s in listed equipment marked to identify the Class 2 power source — you’ve got a Class 2 circuit between the ...

In last month's “Code Basics” article, starting on page 56 of the September issue, we spent most of our time discussing Class 1 circuits. Now, it's time to switch gears and focus on Class 2 and 3.

Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity protection using MOSFET ...

The use of electronic equipment in industrial, commercial and residential environments continues to grow exponentially. All require power to operate and all are significantly impacted by complex power ...

Designing the correct power source is essential and complex, since there is no one typical application. While total automation of power supply design is yet to be achieved, a comprehensive range of ...

A power supply’s characteristics influence the design of a power management subsystem. Two major characteristics are efficiency and performance over its specified temperature range, which may require ...
