What is AccuSine and in which cases can it be used?
It is a solution that can be implemented to reduce harmonics with the variable speed drives (instead of using the usual solutions such as passive filters and DC chokes). Active filters use dynamic switches like IGBTs to stop harmonics from occurring in the first place. However, a customized solution is created for each customer. Therefore measurements on-site must be performed in order to present the customer the suitable solution. The disadvantage of this solution is that they are costly
