94-GHz Large-Signal Operation of AlInN/GaN High-Electron-Mobility Transistors on Silicon With Regrown Ohmic Contacts

Nicolas Grandjean, Jean-François Carlin, Marco Malinverni, Lorenzo Lugani

We report the first 94-GHz (W-band) large-signal performance of AlInN/GaN high-electron-mobility transistors (HEMTs) grown on high-resistivity silicon (111) substrates. A maximum output power density of 1.35 W/mm and peak power-added-efficiency of 12% are ...

Development of a Hybrid MEMS BLDC Micromotor

Yves Perriard, Christian Köchli, Sebastiano Merzaghi

This paper addresses the design of a new hybrid microelectromechanical systems (MEMS) micromotor. It is a small three-phase axial flux brushless dc (BLDC) motor. The stator is developed following the almost-standard CMOS technology rules used for MEMS manu ...

Slotless Permanent-Magnet Machines: General Analytical Magnetic Field Calculation

Yves Perriard, Pierre-Daniel Pfister

This paper presents a general analytical model for predicting the magnetic field of slotless permanent-magnet machines. The model takes into account the effect of eddy currents in conductive regions and notably in conductive permanent magnets without negle ...

Finite Element Model of Electrical Machines Coupled to the Grid Simulation Software

Jean-Jacques Simond, Mai Tu Xuan, Gilles Rosselet

Using a finite element (FE) model of the electrical machine in a grid solver enables us to take the machine nonlinearities into account with great precision in the simulation of a complete system. Three methods are usually used for linking the grid and FE ...

Modeling and Control of a Magnetically Levitated Planar Motor

Alireza Karimi, Roland Longchamp, Marc Kunze

This paper deals with the modeling and control of a magnetically levitated planar motor. The actuator considered has moving coils and stationary magnets. The principal objective is to develop a model which can be implemented in simulation. Therefore, the d ...
