RESUMO:

This paper proposes the use of a Solid State Transformer (SST) AC-DC, isolated, single-phase and
bidirectional, in a photovoltaic mini-generation system with active power of 530 W. To enable the
tracking of the maximum power point (MPPT), a Cúk converter was dimensioned and its input and
output terminals, respectively connected to the photovoltaic array and to a DC bus present in the SST.
The Incremental Conductance (INC) algorithm was used to generate the maximum power voltage
reference. Additionally, the PID technique was also used as a control strategy. To perform the tuning
of this controller, the gain and phase margin was used according to Aström&Hägglund method, for its
relative simplicity. The approach has presented satisfactory results and not required the mathematical
model of the process for calculations. The research shows the numerical simulation results obtained
using the PSIM software, where the effects of the variation of solar irradiance and temperature on the
power generated and supplied to the electrical grid were analyzed.
