This thesis focuses on the design of adaptive active low-frequency ripple controls for a clean-energy power-conditioning mechanism with an aim to achieve both the alleviation of the low-frequency current-ripple of clean-energy sources (e.g., solar photovoltaics, fuel cells, etc), and the improvement of the ac power quality of a power conditioner. First, system descriptions in chapter 2 are given to provide the detailed presentation of experimental equipments. Then, an active low-frequency ripple control for a clean-energy power-conditioning mechanism investigated in chapter 3, which includes a simplified circuit, a neural filter and a total sliding-mode controller (TSMC), can effectively manipulate an active low-frequency ripple control circuit (ALFRCC) to improve the low-frequency ripple phenomena on the bus terminal of the power conditioner. On the other hand, in order to alleviate the power quality pollution of reactive power and harmonic component on the output terminal of the power conditioner under inductive and nonlinear loads, this thesis further develops a dual active low-frequency ripple control for a clean-energy power-conditioning mechanism in chapter 4, which includes a simplified circuit, two neural filters and an adaptive total sliding-mode controller (ATSMC). It can effectively manipulate a dual active low-frequency ripple control circuit (DALFRCC) to improve the low-frequency ripple phenomena on the bus terminal and the output terminal of the power conditioner. Finally, some discussions of numerical simulations and experiment results are given, and some suggestions in the future research are also provided in chapter 5.
