Abstract
The results of an experimental study of multi – stage energy conversion in a "solar battery – multi-stage inverter – load" system are presented. The basic principles of operation of multistage converters and their impact on the efficiency of energy transfer from the solar source to the consumer are considered. An analysis of the operating parameters of the system under various loads was carried out, including changes in the coefficient of useful action (efficiency) and the stability of the output voltage. Experimental data are presented confirming the feasibility of using multi-stage inverters with a high switching frequency and a high voltage conversion factor to increase the efficiency of solar energy systems. The results obtained can be used to optimize the operation of photoenergy plants and develop new methods for converting energy.
