Multilevel Inverter Topology for Switching Loss Reduction

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
In motor drive application, a high switching frequency is required in order to mitigate current harmonics which cause a copper loss. However, the high switching frequency makes the switching loss large. Hence, some switching loss reduction techniques have been studied before. However, they requires complicated circuits. This paper proposes a multilevel

Bounding the loss rates in a multistage ATM switch

1997
We 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.

A turn-on switching losses study in a ZCT soft-switching converter

Proceedings of The 7th International Power Electronics and Motion Control Conference, 2012
This paper presents a mathematical approach of calculating the turn-on switching losses in a ZCT soft-switching converter. In theory, the ZCT scheme enables all main switches and auxiliary switches to be turned on and off under zero-current conditions.

Understanding switching losses in SiC MOSFET: Toward lossless switching

2015 IEEE 3rd Workshop on Wide Bandgap Power Devices and Applications (WiPDA), 2015
Due to the limitation in circuit measurements using current and voltage probes, the conventional ways of measuring switching losses lack the physical insight of the complicated witching process in power devices such as the SiC power MOSFET. This paper seeks to have a better understanding of the dynamic turn-on and turn-off processes of the SiC power ...

Packet Loss Minimization in Load-Balancing Switch

2010
Due 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

Analysis and Mitigation of Valve Switching Losses in Switched Inertance Converters

ASME/BATH 2015 Symposium on Fluid Power and Motion Control, 2015
Switched 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.
