In this article, I’m going to attempt to distill this phenomenon down to its first principles and explain what’s going on in simple terms. I will then present several different ways to reduce the maximum amplitude of the overshoot and the duration of the ringing.

Properly sizing the DC link capacitor for a three phase inverter seems to be a skill that evades most power electronic engineers. The objective of this article is to help you better understand the role of the DC link capacitor in VSIs and how to properly size it based off your requirements.

A Design Validation Plan and Report (DVP&R) is a document that consists of tests conducted to evaluate the hardware functionality of a design to ensure it meets its design specifications or and performance requirement.
Read MorePower Modules or Discretes?
Discrete devices or power modules? This is a question every power electronics engineer faces at some point in their career. I recently had to answer this question for myself and had trouble finding existing literature on the subject, so I thought I’d share my thoughts on the question.
Read MoreSpecter's Design Philosophy
You may have heard the phrase “The whole is greater than the sum of its parts”. At Specter, this saying is more than just an idea: it is our design philosophy.
Read MoreRequirements-Driven System Design Process
After managing the development of two electric racecars over the past two years, I have noticed that the number of students who graduate with solid understanding of the system engineering design process is far and few between. This process is at the core of every engineering project and ultimately drives development forward. All engineers should know how the system design process works, not just project managers.
