Title: Kai Kuehnen: Semiconductor Switching and Fault Detection

Introduction

Kai Kuehnen is an inventor based in Nuremberg, Germany. His patent work includes methods and circuit arrangements for controlling semiconductor switches and detecting fault conditions in half-bridge circuits. The supplied information lists 3 patents and identifies Conti Temic Microelectronic GmbH as his company.

Latest Patents

One of Kuehnen’s latest patents, “Method and Circuit Unit for Determining Fault States in a Half-Bridge Circuit,” describes a way to detect a bridge short circuit. The method compares the actual and setpoint switching states of two semiconductor switches connected in series. It identifies a fault when both switches’ actual states differ from their respective setpoint states.

Another patent, “Method and Circuit Arrangement for Actuating a Semiconductor Switch,” concerns controlled, phased switching. It measures the duration of a switching phase and compares that duration with a specified maximum. If the measured time exceeds the limit, the method switches the semiconductor into a specified operating state.

Career Highlights

Kuehnen’s listed inventions address semiconductor control and fault detection, with a focus on identifying abnormal switching behavior and responding to excessive phase durations. The supplied information associates his work with Conti Temic Microelectronic GmbH.

Collaborations

The listed coworkers include Ulrich Bley and Christoph Hornstein. The supplied information does not specify the nature of their collaboration with Kuehnen.

Conclusion

Kai Kuehnen’s listed patent work focuses on practical methods for controlling semiconductor switches and detecting faults in half-bridge circuits.
