Abstract
This work presents the design of a master-slave sliding-mode control scheme for a modular inverter system composed of N parallel-connected Buck-based single inverters. AC output voltage regulation and balanced current-sharing among the single inverters is achieved by means of a set of switching surfaces and the corresponding sliding control laws. On the other hand, a set of design restrictions is established in terms of inverter parameters and AC output signal amplitude and frequency, this facilitating the subsequent design procedure. Simulation and experimental results for both resistive and nonlinear loads are provided to illustrate the application of the method.
