Figure 1: Power stage of the flyback converter (simplified)

Eleazar Falco, FAE, Würth Elektronik eiSos / Editor, Gerhard Stelzer

Isolated flyback converters often use optocouplers in the feedback loop to regulate the output voltage. As part of the compensation circuit, its parameters such as CTR influence the control loop and must be taken into account in the flyback converter design. The flyback converter is an isolated switching power

Energy harvesting will fuel the 4th industrial revolution

Matthieu Chevrier, Texas Instruments

Today’s zeitgeist – or spirit of the age – within factory automation and process control professionals is to move towards “smart factories,” often referred to as the upcoming fourth industrial revolution. If we look at previous industrial revolutions in order to help prepare for the next one, a pattern em

Inductors for everything

Len Crane, Coilcraft

Electronic devices have been ubiquitous in modern life for some time. So it is perhaps easy to assume that everything necessary has already been accomplished in the world of passive components. As consumers, we are all well aware of faster computers, smaller and smarter phones, brighter and flatter TV screens, an

Precision Counts in IoT

Grainne Murphy and Colm Prendergast, Analog Devices

The Internet-of-Things (IoT) is simply the concept of connecting any device with a sensor or controller to the Internet (and/or to each other). This includes everything from cell phones, appliances, cars machines, components of machines, wearable devices and anything else you can think of. But the principle of
