Analyse of steady-state process in circuits with incommensurable frequencies of voltage sources

The paper presents the study of a process's calculation in circuits with incommensurable frequencies. In such circuits the analysis of processes is realized by the use of an additional independent variable. Definitions of RMS currents, voltages and active power are introduced on the base of double integrals. Calculations of an active power in circuits with two independent voltage sources and a single-phase half-bridge inverter are presented.
