Ninth IEEE International Pulsed Power Conference, 1993
Abstract : Our experiments show energy losses between 2 and 10 times that of the resistive time predictions. The experiments used hydrogen, helium, air, nitrogen, SF6, polyethylene, and water for the switching dielectric. Previously underestimated switch losses have caused overpredicting the accelerator outputs.

Conference Record of the Twenty-Fifth International Power Modulator Symposium, 2002 and 2002 High-Voltage Workshop., 2003
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.
