Description
Summary:This  paper  presents  the  design  of  an  electrical  energy  conversion  system  (EECS)  for  the  use  of  solar  energy  and  its  conditioning  for  injection  of  energy to the commercial power grid. A single-phase full-bridge inverter with transformerless H5 topology coupled to an LCL filter is used. The system is identified using an averaged small-signal state space model; while the used cascade control scheme is tuned by pole placement and includes a maximum power disturb-observe tracking type algorithm of that increases efficiency by  operating  the  system  at  the  optimum  operating  point  of  the  solar  panel.  This  design  describes  essential  technical  aspects  in  the  components  sizing  and selection for experimental development, as well as the control structure design for a good performance to face systems perturbations.
