The tri-state modulation is adopted in order to achieve power decoupling by means of average inductor current. This way it is possible to control the DC/AC conversion independently of the input current. The proposed strategy considers a multiple loop control scheme, where controllers are tuned based on a linearized models of the system. Main experimental results from a 300W prototype are included and discussed.5engmicroinvertersdistributed generationgrid-tie and island modesrenewable energiesTrabalho apresentado em eventoWOS:000400778401001Acesso aberto
