Analysis of the Transient and Steady-State Processes in the Parallel Inverter

This paper deals with the analysis of the transient and steady-state processes in parallel inverters. A set of difference equations, describing the currents and voltages during transient and steady state is obtained and solved. The solution is found in closed form. The roots of the characteristic equations are examined and possible types of transients are discussed. Theoretical and experimental results both for transient and steady-state conditions are compared and satisfactory agreements are found.
