High Power CMOS Power Amplifier for WCDMA
APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006In this paper we propose a power amplifier (PA) for high output power and high linearity WCDMA applications. This PA is designed based on a three-stage configuration and an output stage designed by a multiple gated transistor topology. The test chip is simulated and fabricated with the TSMC 0.18mum CMOS process.

A High Power Welding Rectifier
Transactions of the American Institute of Electrical Engineers, 1934A welding rectifier embodying the ``ignitron'' principle, a recent development in a program of research on mercury arc rectifiers, provides predetermined welding currents for periods of time variable in steps of 20 sec, or less if desired. This paper describes the design and operation of the ``ignitron'' and illustrates its applicability to the ...

A high-power, high-energy pulsed-power generator for high-impedance loads
2011 IEEE Pulsed Power Conference, 2011A high-energy pulsed-power generator, based on a 415 kJ / 22 kV capacitor bank, has recently been developed and tested at Loughborough University. The generator can drive a load having a resistance of between 10 Ω and 40 Ω and a self-inductance between 10 µH and 30 µH, using conventional inductive storage techniques that include a high-voltage ...

High power asymmetrical thyristors
1985 IEEE Power Electronics Specialists Conference, 1985The power loss of fast speed thyristors is relatively high, especially for higher blocking voltage devices. High power asymmetrical thyristors will reduce the power loss up to 40%. In this paper we will discuss the newly developed high power asymmetrical thyristors and their trade-off.
