Title: Ernst Hebenstreit: A Pioneer in Semiconductor Technology
Introduction
Ernst Hebenstreit, based in Munich, Germany, is an accomplished inventor with a remarkable portfolio of 11 patents. His innovative contributions significantly enhance the field of semiconductor technology, particularly in power management and MOSFET applications.
Latest Patents
One of Hebenstreit's latest inventions is a "Semiconductor component having at least one power MOSFET." This patent describes a discretely constructed MOSFET that is switched by a voltage applied between the gate terminal and source terminal. Notably, the source terminal possesses a self-inductance that allows for rapid load current changes, inducing an opposing voltage against the applied gate-source bias. To mitigate this effect, the source contact is linked to an auxiliary terminal, which is largely decoupled magnetically from the source. This design enables effective control of the voltage applied between the gate terminal and the auxiliary terminal, particularly when multiple MOSFETs are connected in parallel, thus suppressing oscillations in the control circuit.
Another significant innovation is his "Circuit arrangement of a self-protecting power switch." Hebenstreit addresses the common issue in power switches where conductive coupling of the control signal inputs can impair functionality. His improved self-protecting power switch employs a first drive unit and a second drive circuit connected via a pulse transformer. This design allows the first drive unit to generate pulse trains based on a control signal, while the second drive unit regenerates square wave signals essential for controlling the power switching stage, effectively enhancing the performance and reliability of power switches.
