A mobile, high-power, high-energy pulsed-power system
2012 IEEE International Power Modulator and High Voltage Conference (IPMHVC), 2012A high-power, high-energy pulsed-power generator, based on a 415 kJ / 22 kV capacitor bank, has recently been developed and tested indoor at Loughborough University. The generator can drive a high-impedance system, generating a total electrical power of many GW while depositing Joule energy of many tens of kJ.

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.

High‐powered automobile stereos
Otolaryngology–Head and Neck Surgery, 1993We measured the owner‐adjusted acoustic outputs of 10 automobile stereo systems, with power ratings ranging between 150 and 600 watts. The sound levels ranged from 107 to 138 dB SPL and 84 to 108 dBA. Most of the high‐Intensity sound was in the 31, 62, and 125 Hz center‐frequency octave bands.

High performance at affordable power
IEEE Micro, 2005Regardless of what chip a team is designing, energy efficiency is probably one of the most important criteria. Achieving high performance at affordable power (and therefore, cost) is the overall system goal across a whole range of products that serve the home, entertainment, scientific, and commercial-enterprise segments of the information technology ...

High power and high efficiency Ka band power amplifier
2015 IEEE MTT-S International Microwave Symposium, 2015A 36 W Ka-band MMIC power amplifier using 0.2 um gate GaN HEMT technology is presented. The power was measured across 27 to 30 GHz with a minimum 30% PAE. A peak power of 40 W at 27 GHz was demonstrated. The MMIC area is a compact 13.5 mm^2 and uses 10.67 mm device periphery in the output stage.

Optical Fiber Communication Conference, 2017
• Optical fibers are an extraordinary active medium… • …but thermal effects cannot be simply neglected anymore. • Recently a serious new limitation has been discovered: Mode Instabilities. • This has quickly become the most limiting factor for the futher scaling of fiber systems.

High-Availability Power for MX
IEEE Power Engineering Review, 1982With modern computer-based analyses it was sible to optimize an extensive power transmission and distribution network for supplying power to MX missile shelter sites. This network would serve some 4600 of these sites, located in suitable contiguous areas, with the shelter sites spaced one mile apart.
