Interference Technology

SAN JOSE, Calif.— Cadence Design Systems, Inc. (Nasdaq: CDNS) today announced a new DRAM verification solution, allowing customers to test and optimize system-on-chip (SoC) designs for data center, consumer, mobile and automotive applications. Using the full DRAM verification solution, which delivers […]

The fast adoption of electric vehicles (EV) was followed by an increased demand for charging stations. To top up the car when traveling, new generations of high-power charging stations are being developed. As a result, as a leader in the […]

Following a strong demand in the market – as an international leading company in the field of electromagnetic compatibility – we provide more connection options for the existing FN9260 and FN9262 filter series.  Exceptional conducted attenuation performance. Option with Stranded […]

Semiconductor die shrinking means that 0.7ns risetimes are now too slow Electrostatic discharges in the real world cover a very wide range: from relatively slow high-voltage events (say, > 1kV peak) to extremely fast low-voltage events (say, < 1kV peak). […]

Ground and power bounce are often ignored as sources of CM noise emitted from all integrated circuit (IC) pins, even if they are static inputs or outputs, digital or analogue, and even sometimes emitted as radiated noise directly from the body of […]

There are many kinds of risk For example: the risk of being late for an appointment; the risk of buying a lottery ticket but  not winning a prize; the risk of designing and manufacturing a new product that might not […]

I recently published this blog, detailing a simple proven method for estimating the radiated E field with  specified test setup. As a result, I received the following feedback… ‘This model is wrong for equipment tested over a ground plane as described. The […]

A simple method for estimating radiated emissions I recently received the following question: How to calculate the radiated E field with following test conditions with an antenna placed 1 meter away from the test setup?: A commercial equipment under test […]

In Part 2 of this blog, the harmonic current distortion of a typical Variable Frequency Drive (VFD) is discussed, as well the possible solutions to the problems that this causes. Active Front End or (AFE) units are also discussed and […]

AC variable frequency drives (VFDs) have been in existence in a number of forms since the early 1970s. In the early 1980s the “pulse width modulated” (PMW) VFD versions began to appear. This form of motor control produced less motor […]
