Math model of a power beam feeding a spacecraft under conditions of intermittent power supply

The paper discusses transmission, reception, conversion and consumption of energy of laser and microwave radiation from Earth or space power plants. It proposes a classification of advanced systems for remote supply of power to spacecraft (SC). It addresses practicability of using remote power supply to SC under various operational conditions. The paper formulates the problem of evaluating the capability of the existing SC power supply systems to receive and convert emissions from additional sources. An analysis of criteria for the quality of pulsed or rapidly varying flow of energy into a SC power supply system. It reviews the structures of typical channels of power consumption in a SC power supply system. An equivalent circuit replacing receivers of pulsed or rapidly changing radiation is described. A math model is proposed for a power consumption channel operating under conditions of intermittent power supply to photovoltaic converters. Math modeling results are presented and analyzed.
