- DESIGN OF A MULTIFUNCTIONAL FLYBACK DCDC CONVERTER WITH CURRENT CONTROLPublication . Santos, Fernando; Jorge, Humberto; Cruz, SérgioThis paper proposes a set of design techniques to build a DC-DC converter for the interconnection of different sources of renewable energy with storage elements and flexible load profiles. This type of multifunctional DCDC converter is essential to provide the dispatch of energy generation to storage connected to the DC bus or allow energy exchange with the AC network, with different decision modes as a function of the state of charge of batteries, with the forecast of the consumption of a house with renewable production. This work emphasizes the application of a method to design switched mode flyback converters with current control capabilities on the output side. The paper discusses in detail the design of the different parts of the converter: the power circuit, the control signals and the auxiliary power supply. The experimental results obtained with the prototype of the DC-DC converter built validate the theoretical analysis and the proposed design techniques. Moreover, the results demonstrate the good dynamic performance of the converter, which exhibits a good current control capability on the output side, being able to follow closely the reference value in a very short period of time, and ensuring at the same time a stable steady-state response.
