Abstract :
This work analyzes the design implications of a control strategy for DC-link based inverters in PV grid-connected systems, based on the association of both discrete-linear and variable structure controllers. The application of this control approach to central and string inverters lead to a comparative in terms of the design restrictions for both topologies which is evidenced by means of simulation results
