DTC in a nutshell Direct torque control, DTC, is a motor control method famous for its superior dynamic properties. Less known is the fact that DTC optimally utilizes the switching frequency to achieve the target: regulation of torque and flux within specified hysteresis band. Thus, DTC contributes to a high Read more…
Triplen harmonics – A devil in your network software tool? This blog post addresses potential “issues” with triplen harmonics when performing a network harmonic study. Positive, negative and zero sequence The theory of symmetrical components tells that a periodic signal can be decomposed into harmonics of positive, negative and zero Read more…
What is the difference between cold and hot commissioning? Recently we got a question in our chat group about cold commissioning. That inspired us to write this short post on the difference between cold and hot commissioning. We will focus on a commissioning of a medium voltage variable speed drive Read more…
