Photovoltaic system with generation control circuit

Photovoltaic (PV) system is considered as a clean and infinite energy source. Usually, several PV modules are connected in series to obtain the required voltage. If some of the PV modules are shaded, the shaded PV modules can only generate very small power or none at all. Since the shaded PV modules cannot operate at the generative level, so the total power from the PV modules greatly decreases even if only small numbers of the PV modules are shaded. This paper proposes a generation control circuit to obtain the maximum power from all of the PV modules including the shaded PV modules by using the multiple output DC/DC converter.
