Abstract. Results of experimental studies of matrix photovoltaic converters
determine the rules for the synthesis of switching circuits that are effective
when working with powerful collimated energy-carrying laser beams is presented.
Features of working with a collimated energy-carrying beam consist firstly in
limiting the aperture of the beam and the need to keep its size and position on
the photoconverting array, secondly, – in the thermal effect of a powerful
collimated beam on the surface of the array, accompanied by a change in the
photovoltaic characteristics of the "hot" elements and thirdly, – in
the heterogeneity of the beam intensity distribution profile on the array
surface, which reduces the photoconversion efficiency relative to beams with a
uniform profile. In some cases, forced stochastization of the intensity
distribution over the surface solves the problem of increasing the efficiency
of photoconversion. Partial and global testing methods for switching circuits
of photoconverter arrays are discussed. Distribution switching schemes for
collimated beams of various profiles are proposed.
Key words:
photovoltaic array, collimated beam, thermal conditions,
current-voltage characteristics, optimal switching.
