Design and Manufacturing of an Electrostatic MEMS Relay for High Power Applications

Christian Köchli, Yves Perriard, Florian Louis Copt, Yoan René Cyrille Civet

This paper addresses the design and manufacturing of a crab-leg based MEMS relay for a high power application. Thanks to a contact resistance lower than 100 mΩ, the relay can hold a current in the order of magnitude of an Ampere without further thermal lim ...

Current Control Strategy for Dynamic Winding Reconfiguration of Slotless Brushless DC Motors

Yves Perriard, Florian Louis Copt, Douglas Martins Araujo

Depending on the winding configuration, the intrinsic characteristic of a motor differs. By reconfiguring the winding, it becomes possible to increase the torque–speed limitation of a motor. Current proposed methodologies for dynamically reconfiguring the ...

Integrated approach for auto-adaptive synchronous motor winding

Florian Louis Copt

The intrinsic characteristic of a permanent magnet synchronous motor is defined by its internal dimensions, its material properties, as well as the power supply used in conjunction with the motor. When an extended operating range is desired but the electro ...

Modeling, Design, and Manufacturing of Microfabricated Coils With High Inductance Density

Yves Perriard, Florian Louis Copt, Yoan René Cyrille Civet, Jasha Poliakine, Douglas Martins Araujo

This paper addresses the design and manufacturing of small scale square planar coils with inductance densities ranging from 2 to 19 miH.mm-2. The design strategy is based on both analytic formulas and finite element method (FEM). Two different manufacturin ...

Electrostatically actuated MEMs relay for high power applications

Christian Köchli, Yves Perriard, Florian Louis Copt

In this paper, a MEMs relay for high power application is investigated. This relay has to hold a current of the order of magnitude of the Ampere and is subject to harsh environment such as high temperature or vibrations which can lead to a premature dysfun ...
