LCI versus VSI Technology: Commercial Comparison In our LCI versus VSI series of articles we have intensively discussed the technical aspects and performance of both high-power drive technologies. Based on your feedback you are interested in a commercial comparison as well. Therefore we decided to write this post on LCI Read more…
Comparison of LCI versus VSI Technology: Myths and Truth We have already discussed the comparison of LCI versus VSI technology quite in detail [1]. However, there is an article [2] in the Internet making a similar comparison of above VFD platforms. Unfortunately, in that article, there are certain statements that Read more…
#LCI versus VSI:Part 4: Comparison (continue) Our series LCI versus VSI belongs to some of the most popular in this blog. We talk about the main medium voltage high power VFD technologies, Load-commutated Inverter (LCI) and Voltage Source Inverter (VSI), and compare them in various aspects. This post is a Read more…
LCI versus VSI:Part 3: Comparison Figure 1: LCI vs VSI In today’s column we continue our popular series ‘LCI vs VSI’ and look a bit closer at the differences between a load-commutated inverter (LCI) and voltage source inverter (VSI). 1. History and references The history of LCI started in mid Read more…
#LCI versus VSIPart 2: Truth and lies about LCI and VSI We continue our series about the high power drive champions LCI and VSI. The introduction [1] last time was a bit longer, but the goal was to provide a good and unbiased overview. There is quite some material regarding Read more…
LCI versus VSIPart 1: Introduction LCI (load-commutated inverter) and VSI (voltage source inverter) are the dominant technologies when it comes to high power medium voltage drives. Each technology has certain advantages as well as drawbacks. Project specific conditions and requirements shall be analyzed before deciding for LCI or VSI. Let’s Read more…
