Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how ...

While simple voltage converters can generate a fixed output voltage from an input voltage, this behavior isn’t sufficient in certain applications. An example is the control of a voltage node that has ...

We have been looking at the history of some HVDC devices such as the mercury-arc valve and the thyristor valve for the past few months. The mercury-arc valve made HVDC transmission possible (1950s), ...

Frederik Dostal explains the rise of the ideal diode and how it can be used to develop more robust power systems.

A power supply’s source, in actual use, is never ideal. The real behaviour, including parasitics, needs to be considered to build a reliable power system. When we use power supplies, we ensure that a ...

Voltage and power integrity are becoming increasingly critical and challenging for chip designers and architects, regardless of which process technology they are using or which market they are ...

Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

A well-organised industrial network operates efficiently within every control panel. At the system's core is an AC-to-DC ...
