Intelligent Power Supply System with Power Transmission via Optical Fiber

Abstract: The digital twin was created and a prototype of the power supply system with power transmission via optical fiber was manufactured. This technology belongs to the field of optical, wireless and fiber optic power transmission (OWPT). Verification of correctness of the digital twin operation was carried out. The task of achieving the maximum possible efficiency of the system at varying load was solved. Its value amounted to 14%. The operability of the search algorithm of the double differentiation system developed for this purpose is shown. The principle of its operation consists in the change of optical energy synchronously with the change of load resistance. This allows to reduce losses in the primary and secondary energy converters. In the area of optimal regulation, the algorithm provides the minimum power supply level necessary for the operation of secondary devices, at which the maximum possible efficiency of the whole power supply system is achieved. The presented work is a part of the program of creating an end-to-end intelligent system of the full production cycle of the product, starting from the design of structures of opto- and photovoltaic converters (PC), up to the manufacture of systems adapted to individual customer requirements. © Pleiades Publishing, Ltd. 2024.
