Title: Innovations of Peter Etter
Introduction
Peter Etter is a notable inventor based in Oberehrendingen, Switzerland. He has made significant contributions to the field of electrical engineering, particularly in the development of current limiters. With a total of 7 patents to his name, Etter's work has had a considerable impact on protective devices used in various applications.
Latest Patents
One of Etter's latest patents is for an overcurrent limiter that utilizes inductive compensation. This innovation focuses on current limiters, specifically PTC resistors, which are essential for limiting short-circuit current when connected in series to capacitors and converter valves. The protective devices that operate with these PTC resistors are designed to work reversibly and respond without arcing. They feature low inductance, making them suitable for space-saving designs. Additionally, these protective circuits are characterized by low loss, shake-proof functionality, and the ability to integrate into existing cooling circuits. The PTC resistors are constructed in a meander shape using porous metal foam or a metal braid or fabric, with electrical contact bridges between their resistor tracks. At least two resistor tracks are electrically connected in parallel and arranged at a small distance from each other, allowing partial currents to flow in opposite directions through the resistor branches. This design can also accommodate grooves in a cooling body or take on a circular shape. A compensation resistor may be included to address uncompensated marginal areas of the resistor tracks, ensuring optimal performance.
