There are few manufacturers of medium voltage drives. Each of them offers different drive topologies with specified advantages and drawbacks. In successively published posts I will provide brief product specification and links to available documentation. At this point I will not compare specific solutions.
In the following posts I will present offer of companies with the [...]
