| Summary: | This paper proposes a novel control topology which enables the setup of a low cost analog system leading
to the implementation of a modular energy conversion system. The modular concept is based on hybrid
renewable energy (solar and wind) and uses high voltage inverters already available on the market.
An important feature of the proposed topology is a permanently active current loop, which assures
short circuit protection and simplifies the control loops compensation. The innovative analogue
solution of the control structure is based on a dedicated integrated circuit (IC) for power factor
correction (PFC) circuits, used in a new configuration, to assure an efficient inverter start-up.
The energy conversion system (control structure and maximum power point tracking algorithm) is
simulated using a new macromodel-based concept, which reduces the usual computational burden of
the simulator and achieves high processing speed. The proposed novel system is presented in this
article from concept, through the design and implementation stages, is verified through simulation
and is validated by experimental results. |
