Magnetics Design for Switching Power Supplies

Figure 1-1 Transformer Equivalent Circuit Introduction Experienced SwitchMode Power Supply designers know that SMPS success or failure depends heavily on the proper design and implementation of the magnetic components. Parasitic elements inherent in high frequency transformers or inductors cause a variety of circuit problems including: high losses, high voltage spikes necessitating snubbers or ...

Simulation and Modelling of Nonlinear Magnetics

Version 1b, August 1994 A procedure for modeling and simulation of arbitrary nonlinear magnetics components is presented. A set of electromagnetic primitives is described as implemented in Verilog-A. The primitives include cores, gaps, and windings that are combined to model ferromagnetic inductors and transformers. The physics of the ferromagnetic core model is described. The model is used to ...

Twisted Pair FDDI Magnetics Overview and Recommendations

The use of twisted pair cable for high speed LAN signalling necessitates the inclusion of transmit and receive magnetics to couple the transmission signal to and from the copper media. The choice of magnetics in a given implementation can have a significant effect on the integrity of the transmission signal. Several important factors must be considered when choosing the magnetics for FDDI twist...

Holographic opto-fluidic microscopy

Over the last decade microfluidics has created a versatile platform that has significantly advanced the ways in which micro-scale organisms and objects are controlled, processed and investigated, by improving the cost, compactness and throughput aspects of analysis. Microfluidics has also expanded into optics to create reconfigurable and flexible optical devices such as reconfigurable lenses, l...
