Title: Michael Rothboeck and Multilevel Inverter Control
Introduction
Michael Rothboeck is an inventor associated with Wels, Austria, and Fronius International GmbH. His patent work addresses voltage balancing in multilevel inverters with split DC links.
Latest Patents
The available information lists 1 patent for Rothboeck: “Method for Controlling a Multilevel Inverter with a Split DC Link.” The method calculates a modulation signal from the difference between the actual electrical power at the DC-link capacitors. It uses an even-harmonic signal related to the inverter’s output voltage or current, then superimposes that signal on the setpoint used to control the inverter’s output. The approach is intended to improve voltage balancing across the DC-link capacitors.
Career Highlights
