Abstract
In this work, a fiber-based optical powering (or power-by-light) system capable of providing more than 1?W is developed. The prototype was used in order to power a shunt regulator for controlling the activation and deactivation of solar panels in satellites. The work involves the manufacture of a light receiver (a GaAs multiple photovoltaic converter (MPC)), a power conditioning block, and a regulator and the implementation and characterization of the whole system. The MPC, with an active area of just 3.1?mm2, was able to supply 1?W at 5?V with an efficiency of 30%. The maximum measured device efficiency was over 40% at an input power (Pin) of 0.5?W. Open circuit voltage over 7?V was measured for Pin over 0.5?W. A system optoelectronic efficiency (including the optical fiber, connectors, and MPC) of 27% was measured at an output power (Pout) of 1?W. At Pout?=?0.2?W, the efficiency was as high as 36%. The power conditioning block and the regulator were successfully powered with the system. The maximum supplied power in steady state was 0.2?W, whereas in transient state, it reached 0.44?W. The paper also describes the characterization of the system within the temperature range going from ?70 to +100?°C. Copyright © 2011 John Wiley & Sons, Ltd.
