Bounding the loss rates in a multistage ATM switch
1997We study the cell loss rates in a multistage ATM switch. We present some numerical computations for small configurations which prove that first order approximation may not be accurate. We present stochastic bounds for these loss rates using simple arguments which lead to models easier to solve.

Packet Loss Minimization in Load-Balancing Switch
2010Due to the overall growing demand on the network resources and tight restrictions on the power consumption, the requirements to the long-term scalability, cost and performance capabilities appear together with the deployment of novel switching architectures. The load-balancing switch proposed in [1,2] satisfies to the above requirements due to a simple

Micromachined low-loss microwave switches
Journal of Microelectromechanical Systems, 1999The design and fabrication of a micromechanical capacitive membrane microwave switching device is described. The switching element consists of a thin metallic membrane, which has two states, actuated or unactuated, depending on the applied bias. A microwave signal is switched on and off when the membrane is switched between the two states.

A zero switching loss matrix converter
Proceedings of IEEE Power Electronics Specialist Conference - PESC '93, 2002A low loss bidirectional switch set is proposed for a matrix power converter. The proposed switch is able to turn on at zero current and turn off at zero voltage to achieve almost zero loss and soft switching. Hence, a simple hysteretic current control can now be applied directly to a matrix power converter without adding any additional snubber circuit

Determining the losses in spark gap switches
7th Pulsed Power Conference, 2005The variation in losses in gas plasma switches is difficult to measure directly for most practical switches. The approach usually adopted is to measure the voltage across the switch and the current passed through it. The problem area is measuring the voltage, which fast becomes very small compared to the voltage applied to the system as the current ...

Low loss ferroelectric microwave switch
1962 International Electron Devices Meeting, 1962A low loss ferroelectric microwave switch has been developed recently for operation at L-band frequencies. The switch is constructed in strip transmission line using (Ba-Sr)TiO 3 as the active element. It is capable of switching in less than 0.1 usec and provides isolation in excess of 20 db with an insertion loss of less than 0.7 db over a band of 20 ...

The nanoscale analysis of MOSFET switching loss
Semiconductor Science and Technology, 2009A nanoscale analysis of MOSFET switching loss is presented. A new analytical method based on drift diffusive and quantum transport principles with a non-equilibrium Green's function method is proposed. For the first time, the switching energy in a MOSFET is expressed as a function of the dc bias, operating frequency, dimensions, doping concentration ...

Analysis and Mitigation of Valve Switching Losses in Switched Inertance Converters
ASME/BATH 2015 Symposium on Fluid Power and Motion Control, 2015Switched inertance converters use digital valves to exploit the inertia of a flow in order to trade flow for pressure or vice versa. These components can be used to efficiently match load and supply pressures, avoiding the energy wasted by using resistive valves.

Switching losses of the cryogenic MOSFET and SIT
Cryogenics, 1990Abstract Cryogenic MOSFET power conversion may be feasible in the near future for certain applications where high power pulses are required at low duty cycles. The eventual availability of high temperature superconductors will only enhance the implementation of such circuits based on low temperature electronics.
