抄録

A 2-W supply optical powering system that maintains electrical isolation is described. The output power of this system is stable and higher than that of conventional systems, and is not affected by environmental stresses, such as bends in the optical fiber or increased PV cell temperature, owing to its feedback control function. The system mainly consists of laser diodes, optical fibers, photovoltaic (PV) cells, and a feedback control circuit, and can deliver 2 W of electrical power. In the feedback control circuit, the PV cell output current is compared to the target current, and the laser output is controlled to equalize them. The system also has a safety function that shuts down the laser if an optical fiber is cut. The system was tested under a high-voltage condition, and the results indicate that it will be useful for driving sensors and measurement equipment used in high-voltage environments.
