Microgrid-systems with alternative energy sources in which multilevel inverters are used are becoming more widespread. Possible circuit implementations of multilevel inverters for thus systems are shown. A comparative analysis of the energy parameters of multilevel inverters using various modulation algorithms is presented. important requirement of multilevel voltage inverters is to ensure high quality output voltage, as well as ensuring minimum power loss and maximum efficiency. An overview of known modulation algorithms for output voltage generation in multilevel inverters is presented. The analysis of existing algorithms was performed and the choice of the optimal algorithm for use in the scheme of solar power plants was carried out.
