• AC/AC converter
• Galerkin's method
• extension of differential equations
• double Fourier series

This paper presents a numerical-analytic method intended for calculations of steady-state processes in AC/AC converters that are described by nonstationary and periodical differential equations. Differential equations are extended by an additional, independent variables of time, corresponding from different pulsation. Approximation solution is obtained using the method Galerkina in which the basis functions are double Fourier series. The results of the presented calculations are derived from an example of a Boost converter.
