This paper presents the analysis of electromagnetic processes in a bidirectional DC-AC converter based on an asymmetric inverter with magnetically coupled inductors, as well as the determination of its parameters aimed at improving energy efficiency. The study is based on the state-space averaging method and simulation modelling techniques. As a result, analytical expressions for calculating currents in the asymmetric inverter with magnetically coupled inductors during switching intervals are derived. The relationship between the inductances of the inductors and the parameters of the input and output power sources is established, under which circulating currents in the inverter circuits are eliminated, resulting in reduced static power losses in the converter. In this research, new analytical and graphical relationships are obtained for the operation of a bidirectional DC-AC converter in active and reactive power transfer modes, thereby extending previous models of asymmetric DC-DC converters. The derived relationships enable improved converter efficiency at the design stage by minimizing power losses caused by circulating currents through optimal parameter selection.
