Abstract
Optically powered system is a revolutionary new power delivery system, in which optical power is delivered over fiber to photovoltaic power converter, where optical power is transformed into electrical power. Therefore the system is inherently immune to RF, EMI, high voltage and lighting effects. Capable of powering electronic circuitry by optical fiber, this technology has been validated in industries such as electric power, communications, remote sensing and aerospace. To a large extent, photovoltaic power converter is a key component that decides the performance of optically powered system. In this paper, the commonly used GaAs photovoltaic power converter is studied and tested. Parameter values like open circuit voltage, short circuit current, maximum output power, conversion efficiency and the optimum load resistance are obtained through experiment, which can be severed as important reference while choosing or designing DC-DC converter.
