Germany’s roughly 30,000 wind turbines currently produce a good 50,000 megawatts of electricity for households and companies. The expansion of wind energy both onshore and offshore is helping determine the pace and success of the shift in energy policy introduced at the beginning of the decade – a move away

Dissipating the heat generated by certain components is a key part of electronics design. Consequently engineers need to be sure that they put an effective thermal management system in place in order to ensure that operational reliability is maintained. There are a variety of different technologies that can

Essential performance, voltage dips and medically certified power supplies

TDK-Lambda Certified Medical Power Supplies

Although essential performance is covered in IEC 60601-1 2nd edition, the 3rd edition defines it in greater detail as “the performance necessary to achieve freedom from unacceptable risk”.  It is up to the manufacturer to determine if a loss of performance or functionality will

When designing to meet the requirements of EN 60335, engineers have to adopt a different mind-set. Compared with the familiar IT and medical standards, not only are some design limits different but also the potential users and end products are much more varied. Unusually in safety evaluation, multiple faults

Addressing Differential and Common Mode Noise With Innovative Dual-Mode Choke Technology

CMF Series Dual Mode Chokes

Circuit designers must deal with many types of noise: internal, external, RF, line frequency and more. Noise can be a limiting factor in system performance and so must be addressed and minimized. The question is “at what cost and effort?”  Is it better to sacrifice performance or cost?  In either

Train Your Fitness Monitor to Deal with Any Lighting Conditions

Figure 1. Wrist-Worn Health and Fitness Monitor

With the proliferation of wearable health monitors among fitness enthusiasts, it may be worth posing the following question: Is the data being produced by these devices always accurate and reliable? In the same way that automobiles encounter real-world driving conditions vastly different from the laboratory

Self-Balancing Supercapacitor Reliability Testing Performance

Figure 1. This graph pair represents Capacitance vs. Time and ESR vs. Time for the SCMT22C505MRBA0 at rated voltage (5V) for 4,000 hours at 85°C.

Supercapacitors are increasing in popularity amongst board-level components. In turn, there is now greater demand for supercapacitor reliability testing data, as sub-ppm component failure rates are critical for minimizing and eliminating PCB rework. The following case study addresses basic supercapacitor

No Inductors Required

Figure 1. Simplified Charge Pump Block Diagram of a Voltage Inverter

A fundamental axiom for switching power supplies is that they must not generate a lot of noise. Accordingly, quiet, well-regulated power supplies are important for optimum performance in many circuit applications. In order to attain this level of performance it is critical to be able to mitigate any noise generated
