GaAs converters for high power densities of laser illumination

Progress in Photovoltaics: Research and Applications, 2008
AbstractPhotovoltaic power converters can be used to generate electricity directly from laser light. In this paper we report the development of GaAs PV power converters with improved conversion efficiency at high power densities. The incorporation of a lateral conduction layer (LCL) on top of the window layer resulted in a considerable gain in ...

Photovoltaic laser power converters for wireless optical power supply of sensor systems

2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE), 2016
Optical power transmission (also called power-by-light) is an elegant solution to power wireless sensor nodes. At the sensor, optical power in form of monochromatic laser light is converted to electricity by photovoltaic laser power converters. These photovoltaic cells are optimized for the monochromatic wavelength of the light — opposed to solar cells,

Application of Series Resonant Converters in Laser Power Supply

2010 International Conference on Electrical and Control Engineering, 2010
The series resonant converter is a kind of DC to DC converter. The paper introduces the principle of the half bridge series resonant converter and the application of the half bridge series resonant converter in laser power supply. The series resonant converter has the high converting frequency and its output waveform comes near to the sine wave.
