| Summary: | The paper deals with an analysis of steady-state behaviours in inverter circuits. Transient and steady-state processes in inverter circuits are described by differential equations with periodical coefficients. The control of inverter switches and a load is realised by signals which frequencies are independent. These frequencies are incommensurable. In order to obtain steady-state periodic solutions ordinary differential equations are expanded into partial differential equations with two independent variables of time. The solution of partial differential equations is found by calculating a periodic boundary condition for an arbitrary period in the domain of two time variables. Obtained functions are used for forming a time delay equation. This equation is solved by the use of the Galerkin method with sinusoidal weight and basis functions. The result of a calculation is represented in the form of the Fourier series. The periodic boundary condition and steady-state process for a boost inverter with varied load are presented.
