Selection of the basic parameters of the grid-tied inverter with PWM in the mode of tracking the reference signal

Abstract

A method has been developed for calculating the main parameters of grid-tied inverters with PWM for set values of the harmonic ratio of the output voltage. Recommendations on the choice of LC filter parameters are described for optimal design of grid-tied inverters. Recommendations are based on the results of an experimental study of the spectral composition of the output voltage.
