Semiconductor Thermoelectric Converters of Alternating Current Signals

Journal of Electronic Materials, 2011
Measuring converters have been developed based on Bi2Te3 solid solutions optimized for temperature and temporal stability of the basic thermoelectric parameters (thermal conductivity, electrical conductivity, and the Seebeck coefficient). Semiconductor material was grown by the vertical zone melting method.

Ultrahigh-speed compound semiconductor mode-converters

Opto-Canada: SPIE Regional Meeting on Optoelectronics, Photonics, and Imaging, 2017
JGKB Photonics Inc. and the University of British Columbia present recent results for an alternative type of electro- optic modulator, the integrated-optic mode-converter [1]. The integrated-optic mode-converter has the potential to bring the drive-voltage of electro-optic modulators down to the 3 to 4 V range while preserving the benefits typically ...

Superconductor/Semiconductor Hybrid Analog-to-Digital Converter

IEICE Transactions on Electronics, 2008
We have designed a superconductor-semiconductor hybrid analog-to-digital (A/D) converter and experimentally evaluated its performance at sampling frequencies up to 18.6GHz. The A/D converter consists of a superconductor front-end circuit and a semiconductor back-end circuit.

A User Looks at the Semiconductor Converter

IEEE Transactions on Industry and General Applications, 1968
As one of the largest users of power converter equipment in the world, Alcoa has had a profound interest in the development of the semiconductor power converter. This paper reviews the application of large converter equipment, starting with the first major unit installed in the United States at Alcoa's Badin Works in North Carolina, and traces ...

Transmission-type semiconductor bolometric microwave power converter

Measurement Techniques, 1986
The main problem encountered by designers of reference measuring devices for moderate microwave power levels is how to overcome the contradiction between small dimensions of the waveguide channel and the need to dissipate comparatively high power in the absorbing sensitive element.

High-Power Installations Using Semiconductor Devices, Interactions Between Semiconductors and Converters

1982
Power electronics has found a wide variety of applications in the fields of power ge­neration, transmission and distribution, in industry and for traction drives. The speed, direction, and extent of future progress in the development and application of power electronics depend very strongly on the progress made in semiconductor tech­nology, both ...

Semiconductor models for a 20 MHz converter

Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990
The semiconductor models described allow quantitative results not possible with the simple switch models of conventional circuit simulations. Average and instantaneous semiconductor dissipation and their temperature behavior can be calculated. At megahertz frequencies, currents may be difficult to measure without disturbing the circuit.
