Conceptual design of a novel arcless controlled switch

2009 
A new current controlled switch is introduced in this paper and its conceptual design approach is described. The device works based on the motion of a liquid conducting medium and uses the built in electromagnetic quantities instead of external feedback signals to control the desired quantities. At first, the proposed electromagnetic structure of the device and the design criteria are introduced. After that the resulted Lorentz force on the moving conducting medium is calculated using FEM software and the motion equations of this conducting medium are solved using a numerical method. Accordingly the design criteria, which are converted to a set of mathematical and physical constraints, can be checked in each time step and the structure or quantities can be modified where needed. Finally some modifications are applied to the design and the switch operation is simulated for some different operating points.
