Magnetic levitation refers to the object using electromagnetic force to overcome gravity and achieve a stable suspension or random equilibrium state without mechanical contact.
This paper presents a System-Verilog behavioral model for charge-pump PLLs based on piece-wise constant (PWC) real number modeling and table lookup. The proposed model exploits the sampled nature of the PLL where most of its analog behavior takes effect during the phase detection, and remains almost constant during the rest of the reference cycle. The PLL model simulation run time takes only 1 second,...
This paper presents a double-ladders circuit model of transformer winding for use in frequency response analysis (FRA) to diagnose the windings deformation. This model considers the nonlinear behavior of frequency-dependent parameter and core loss. A lumped parameter circuit model includes the axial and radial ladder network which are regarding to the winding discs and the eddy current paths of magnetic...
High temperature superconducting (HTS) cables for large current transmission in general have a multilayer structure consisting of parallel connected tapes, twisted in each layer. The control of current distribution among these layers is an important issue for design and optimization of a HTS cable because this would significantly affect the current transmission capacity and power losses. The pinned...
