Title: The Innovative Contributions of Stefan Zeh
Introduction
Stefan Zeh is a prominent inventor based in Wangen, Germany. He has made significant contributions to the field of electrical engineering, particularly in the area of converter control and motor operation. With a total of 10 patents to his name, Zeh's work has had a substantial impact on the industry.
Latest Patents
One of Stefan Zeh's latest patents is a method for controlling a converter. This method involves controlling a three-phase converter with a voltage intermediate circuit through pulse-width modulation for supplying a polyphase system, specifically a three-phase machine. The converter operates using at least two different modulation methods, which include single-phase switching, two-phase switching, and three-phase switching. The invention allows for changeovers between these modulation methods based on the operating state of the polyphase system.
Another notable patent is a method of error detection when controlling a rotating-field motor. This method focuses on fault identification during the operation of a rotating-field motor using a pulse-controlled inverter. It determines electromagnetic state variables of the motor through a mathematical model in space-vector form. The invention analyzes the space vector of an uncontrolled state variable for a spectral component at twice the frequency of the rotating field. If this spectral component is present, it indicates a partial turns short in the stator windings.
