Abstract :
This work is devoted to the central-limit control (CLC) sliding-mode design of a modular system composed by N parallel-connected 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 the inverter parameters and the AC output signal amplitude and frequency, this facilitating the subsequent design procedure. Simulation and experimental results for three parallel-connected inverters are provided to illustrate the application of the method.
