Electromagnetic Analysis and Validation of an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

The ironless inductive position sensor is a linear position sensing structure, which exhibits intrinsic immunity to external magnetic fields since it is characterized by air-cored windings. This new solution may be of major interest for applications where ...

Modeling of High-Frequency Electromagnetic Effects on an Ironless Inductive Position Sensor

Yves Perriard, Alessandro Danisi, Alessandro Masi

The ironless inductive position sensor (I2PS) is a five-coil air-cored structure that senses the variation of flux linkage between supply and sense coils and relates it to the linear position of a moving coil. In air-cored structures, the skin and proximit ...

Study on the Reversible DC-DC Converter as Interface between Low and Medium Voltage DC Networks

Alfred Rufer, Stephan Kenzelmann, Carlo Arrioja

This paper introduces an isolated reversible DC-DC converter with a particular topology, which benefits from both the NPC (neutral point clamped) structure and the series-parallel connection of converters. The key property of the proposed topology is the o ...
