It may have gone somewhat unnoticed but for the first time ever, Ansys released software into the open source late last year. The software is PyAnsys, a family of Python packages providing a new, unified programmable interface to the company’s proprietary simulation stack. Learn more about this development.

I do not know if there was a legitimate reason for this request, but I was once asked to determine the turns ratio of a power transformer inside a sealed, DC-DC converter module.  In any case, there is not much usable information since the module is sealed, but we can apply a simple trick. Check out this latest installment in Extreme Measurements.

Impedance is the most fundamental and important electrical property of any component. With a very simple technique, anyone can simulate the impedance of any circuit in seconds using any version of SPICE, for free. Read on to learn more.

This extreme measurement seems more impossible than difficult.  The traditional stability assessment method for voltage regulators is the Bode plot.  Access to the control loop is required and a small signal is injected into the control loop, usually via a resistor, placed at the top of the voltage sense divider. Without access to this voltage divider, there isn’t a place to inject a signal into the control loop, and therefore the Bode plot is seemingly impossible…

Now that I am teaching full time and have a number of undergraduate and graduate students doing weekly project reviews, I listen to more presentations than I give. I find myself giving the same feedback over and over again. So, I thought I would share my eight most common comments and tips to engineers giving presentations.

In this Extreme Measurement Example, see how measurements were used to resolve the shield resistance issue, where the authors redesigned the PCB to clear the DUT contact, but also identified alternate solutions in the event they could not wait for a new PCB.

This first post in a new blog series, Extreme Measurements, introduces how an extreme measurement is defined. Find out how your extreme measurement story can end up on SIJ!
