Title: Norbert Preusse: Innovator in Current Sensing Technology
Introduction
Norbert Preusse is a notable inventor based in Alzenau, Germany. He has made significant contributions to the field of current sensing technology, holding a total of 4 patents. His innovative work has paved the way for advancements in measuring electrical currents with precision.
Latest Patents
One of his latest patents is a Current Sensor, which comprises a magnetic module. This sensor includes a primary conductor, a compensating winding, and a magnetic field probe that are magnetically coupled. The primary conductor carries the current to be measured, while a driving circuit produces a triangular current injected into the compensating winding. An evaluation circuit switches the output signal from a first to a second output level based on a zero crossing of the signal provided by the magnetic field probe. The output signal is pulse-width modulated, depending on the intensity of the current being measured.
Another significant patent is a measuring method and arrangement for measuring currents with a large dynamic range. This method involves switching into a high-current mode when a current threshold value is exceeded and switching into a low-current mode otherwise. The low-current mode includes feeding a first current pulse to a compensation coil, which drives a magnetic core in one direction until magnetic saturation occurs. It also involves measuring a first primary current value after the current pulse is disconnected, followed by feeding a second current pulse in the opposite direction and measuring a second primary current value. The corrected primary current value is then determined as an average of the two primary current values.
