Abstract
This article analyzes a solar photovoltaic system composed of a Series Resonant Active Dual Bridge DC-DC Converter and its control blocks. These converters are particularly attractive for renewable energy applications due to their high switching frequency with low switching losses. The converter analysis consists of an equivalent circuit using the Fourier series from that obtaining the control parameters. The classic MPPT Perturb-Observe algorithm is also designed and analyzed to add the Fuzzy Logic algorithm and shorten the search time for the maximum power point and reduce the oscillation around the maximum power point, which is produced by the Disturb-Observe algorithm once that point is found. Finally, the results of the simulations performed with PSIM software for a 500 W solar panel prototype are presented. The results of the classic Perturb-Observe algorithm are compared with the Perturb-Observe modified algorithm with fuzzy logic, giving a better performance than the classic one.
