On the Influence of Switch Resistances on Switched-Capacitor Converter Losses
IEEE Transactions on Industrial Electronics, 2012The contribution of switch resistances to the losses in switched-capacitor converters (SCC) is reevaluated. The results reaffirm the crucial role that the switch resistances play in the design of open-loop and regulated SCC.

Losses in soft-switched and hard-switched voltage inverters
2003 IEEE International Symposium on Industrial Electronics ( Cat. No.03TH8692), 2004This paper introduces an adequate loss model, based on the experimental results, which can be used to estimate the losses in hard-switched and soft-switched inverters. As an example and considering the use of IGBTs, it compares the losses produced by hard-switched, auxiliary resonant commutated pole (ARCP) and quasi-square-wave (QSW) inverters for ...

A Simplified SVPWM Algorithm with Reducing Switching Losses
Proceedings of the 2020 2nd International Conference on Robotics, Intelligent Control and Artificial Intelligence, 2020Aiming at the problems that the traditional two-level space vector pulse width modulation algorithm is of complex calculation and high switching losses, a two-level SVPWM algorithm that can reduce the switching losses and simplify the algorithm implementation process is proposed.

Investigation on Switching Energy Losses in Reversely Switched Dynistor
IEEE Transactions on Power Electronics, 2014This paper presents theoretical and experimental results on the energy loss characteristics of reversely switched dynistor (RSD) under high-current conditions. Theoretical analysis was performed based on a 1-D modified model by taking account into the carrier-carrier scattering effect and auger recombination effect during the conducting process.

Prediction of switching loss variations by averaged switch modeling
APEC 2000. Fifteenth Annual IEEE Applied Power Electronics Conference and Exposition (Cat. No.00CH37058), 2002An analytical averaged equivalent circuit model is derived revealing how dominant loss mechanisms vary with power converter operating point in a PWM converter. The model is based on the operational characteristics of power diodes and IGBTs. Laboratory experiments support the derived model and confirm that IGBT current tailing and diode reverse-recovery

Loss of Gas7 Is a Key Metastatic Switch in Neuroblastoma
Cancer Research, 2021Abstract Metastatic spread to distant tissues and organs is responsible for most cancer-related mortalities. Changes in the invasiveness ability of metastatic tumor cells often come with significantly altered gene expression profiles compared with primary tumor cells. Identifying the main actors involved in the metastatic switch of tumor

Determination of switching losses in IGBTs by loss-summation-method
IAS '95. Conference Record of the 1995 IEEE Industry Applications Conference Thirtieth IAS Annual Meeting, 2002The exact determination of switching losses in power transistors is still an important problem. This paper treats investigations on switching losses in insulated gate bipolar transistors and assigned freewheeling diodes at hard switching commutation. Especially, a new technique, the loss summation method, is presented.

On Loss Mechanisms of Complex Switched Capacitor Converters
IEEE Transactions on Circuits and Systems I: Regular Papers, 2015In this paper the power losses of efficient capacitive converters with multitude transfer ratio values are discussed. The loss mechanism circuits, based on general transposed series parallel (GTSP) topology, is studied and the losses are calculated, which in turn enables the “bottlenecks” to be identified and overcome.

Cell loss performance of the Gauss ATM switch
[Proceedings] IEEE INFOCOM '92: The Conference on Computer Communications, 1992The authors present a performance study of the Gauss asynchronous transfer mode (ATM) switch with respect to cell loss. The Gauss switch is a recently proposed, high-performance, output buffered ATM switch that can easily be implemented. In general, if an ATM switch suffers from cell loss, the exact behavior of this cell loss as a function of ...

Optimization of switching losses and EMI in a Cuk converter
Proceedings of International Conference on Power Electronics, Drives and Energy Systems for Industrial Growth, 2002Switching mode power supplies are significant sources of electromagnetic disturbances, especially conducted EMI, due to the high current and voltage derivatives caused by the high frequencies used today in order to reduce the size of electromagnetic and capacitive elements.
