Magnetic field sensor for measuring direction of a magnetic field in a plane

Radivoje Popovic, Pavel Kejik

A magnetic field sensor for measuring a direction of a magnetic field in a plane comprises a sensing structure (4) comprising a ring-shaped well (10), a plurality of contacts (11) of equal size placed at equal distance from each other along the ring-shaped ...

The Active Self-controlled Free-wheeling Management Principle Applied to Reverse Recovery Losses Reduction

Alfred Rufer, Philippe Barrade, Daniel Siemaszko

Several works suggest the imminent appearance of bidirectional active devices. The promised performances go in the direction of a reverse recovery effects reduction and efficiency improvement. Our purpose is the study of an active management for switches t ...

New self-switching mechanisms for active bidirectional switches

Alfred Rufer, Philippe Barrade, Daniel Siemaszko

The self-switching principle is a synthesis of synchronous type switching and switch inner protection mechanisms. Both switch ON and switch OFF are performed on the base of current and voltage measurement across the switch. Applied to an active bidirection ...

Three-Level Quadratic Non-Insulated Basic DC-DC Converters

Alfred Rufer

This paper presents a family of three transformerless converters (buck, boost and buck-boost) with two specific characteristics: the quadratic static gain as a function of the duty cycle ratio, and the division of the higher voltage level between the two s ...

Study of novel electronic conductors : the case of BaVS3

Neven Barisic

This thesis presents the results of a concerted effort to understand the complex array of physical properties exhibited by the BaVS3 family of materials. As a 3d1 system, BaVS3 displays a unique collection of correlation-driven phenomena, including a metal ...
