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

Fast, accurate, & efficient test at low power is key

Robert Green, Keithley Instruments, a Tektronix Company

It has been predicted that, within a decade, the Internet of Things (IoT) will grow to encompass billions or even trillions of wireless devices and sensors. However, that growth will depend to some degree on the ability of their manufacturers to drive down the cost of each of these devices. At the same time, ho

Dimmer trade-offs in LED lighting

Hubie Notohamiprodjo, Dialog Semiconductor

In the US alone, it has been estimated that there are over 150 million installed residential dimmers designed for incandescent or halogen bulbs that operate directly from the mains voltage. LED bulbs ideally should be able to drop into those existing sockets and provide a smooth, flicker and shimmer-free lighting ex

Using a smart LED module for special purpose and general lighting

Valentin Kulikov, Futuro Lighting

A smart DC LED module connects most recent LED technology together with smart DC drivers, offering a ready-made solution for fixture producers, researchers, and hobbyists. Such a module is usually populated on a metal-core PCB, implementing LEDs and a high-efficiency driver with thermal foldback and dimming. Ad

Low Power Wireless Sensing Spurs IoT Development

Joy Weiss, Ross Yu, and Jonathan Simon, Dust Networks Product Group, Linear Technology

Low power wireless technology is enabling substantial cost reductions for traditional wired sensing systems, and opening up new possibilities for sensor networking that simply could not be done with wires. Low power wireless sensor networking (WSN) standards, particularly mesh architectures that utilize time-synchronized ch

Pumped-storage facilities turn to polyurea coatings and linings

Del Williams, VersaFlex

As renewable energy demand rises in the U.S., the demand for hydropower pumped storage has risen with it. Forty pumped storage plants provide more than 22 gigawatts (GW) of storage capacity in the U.S., according to the U.S. Energy Information Administration. Recently the Federal Energy Regulatory Co

PoE is perfect for LED lighting

Alec Makdessian and Thong Huynh, Maxim Integrated

Power-over-Ethernet (PoE) is a technology used in wired Ethernet local area networks (LANs) that delivers power over the same cable that delivers the Ethernet data. This reduces the number of cables that must be laid to install a network and power the devices connected to it. It also makes it easier to maintain an
