Thyratrons are limited in lifetime and maximum repetition rate. For some applications it is necessary to replace the thyratron by a semiconductor switch. Therefore it is necessary to compress the pulses by nonlinear inductances. In a magnetic pulse compression network three main losses exist.

Modeling of losses in switched reluctance machines
38th IAS Annual Meeting on Conference Record of the Industry Applications Conference, 2003., 2004Switched reluctance motor (SRM) performance prediction requires the modeling of iron losses. The iron loss model in this paper separates the iron losses into two components, eddy-current and hysteresis losses, and models the losses as a function of the derivative of flux density. The model is suitable for the nonsinusoidal flux densities in the SRM and

Switching loss reduction of MOSFET using switching assist circuit
2015 IEEE International Conference on Industrial Technology (ICIT), 2015This paper describes a new high-efficiency and high-speed switching method of a MOSFET using a switching assist circuit fed by the gate drive power supply. By applying the proposed circuit to a chopper and an inverter, a turn-off time of the MOSFET can be effectively reduced, which allows a higher-frequency operation and reduction of the turn-on loss ...

Loss reduction by network switching
IEEE Transactions on Power Systems, 1988Systematic and fast switching for the purposes of reducing losses in power transmission networks is treated as an optimization problem whereby switching is to be understood in a general and comprehensive way. Injected currents applied to a base network are used to model the switching operation.

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.

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 ...

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

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.
