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
Combining ultra-precise control with long operating life, stepper motors have become a critical building block in motion-based applications ranging from white goods to factory automation and robotics to printers and point-of-sale equipment. For the designer, the challenge is to ensure the best combination of pe
Piezoelectric elements have traditionally been used primarily in applications in the audio industry, operating in the human audio range (nominally 100 Hz to 18 kHz). However, subsequent improvements in device characteristics have extended their usefulness into markets which demand much-higher performance. For ex

DC-DC converter modules have been around a long time and can be found in most power conversion stages of virtually every application today. As their use evolved to changing application requirements so did the design approach used to construct them.
One of these trends meant that in order to preserve conversio
The ability to make consistent measurements of RF or microwave power levels is vital to developing effective radio systems and networks. This article explores how different approaches affect the resultant measurements.
The test case compares various approaches to making average power measurements of contin
Lots of things are currently changing: Digital transformation is in full swing, changing our daily lives and demanding new business models. Many countries are facing economic and social challenges. Let’s look at how this effects distribution and what companies like Rutronik are doing to continue to move forward in
Microfabrication operations such as metal lift-off, stripping, etching, plating/coating, cleaning, and de-bonding are typically wet processing procedures. Yet, selecting the equipment to perform those procedures most efficiently and cost-effectively is often not a simple matter (see Figure 1). In most cases, the

Interest in electric vehicles (EVs) and hybrid electric vehicles (HEVs) is growing steadily as battery technologies improve and the driving range of such vehicles increases. Perhaps as important, EVs/HEVs offer a “green” alternative to traditional vehicles powered by internal-combustion gasoline engines.
EVs and HEVs r
We are all aware about self-driving cars, and all exciting projects the automotive industry is engaged in, but very few have heard about unmanned ship and projects to operate large fleets of vessels navigating from dock to dock without operational crews (see Figure 1). In early stages, projects such as Maritime Un
Resolution is the most obvious battleground on which rival television and display manufacturers fight. Consumers have been willing to pay a premium for high-definition HD) displays, and, more recently, for 4k displays. Eventually, ultra-high definition 8k displays are expected to supersede the current generation of
