The scientific article is devoted to modeling a single-phase two-level voltage inverter (AIV) with pulse-frequency modulation (PFM). The model is implemented in MATLAB R2019a using blocks from the Simulink/Simscape library. The basic elements of the Simscape library are described. A pulse-frequency modulation (PFM) scheme was developed and modeled using blocks from the Simscape library. The obtained PFM diagrams showed that the frequency in the middle of the PFM period is 3 times higher relative to the edges. The current and voltage diagrams of the active and active-inductive load in the AIV are also obtained.
