Abstract
Controller apparatus with MPPT tracking for controlling an electric power generation system comprising two identical sub-sections of a photovoltaic field, connected to two respective identical switching power converters, the two converters being controlled by two respective periodic controlling signals and the outputs of the two converters being connected in parallel. The controller apparatus comprises a first and a second current sensor for detecting the output currents of the two converters, a subtractor capable to receive the two current detection signals and to generate a difference signal, an amplifier capable to amplify the difference signal by a constant gain k, and a low-pass filter capable to filter the amplified difference signal, a proportional-integral controller for controlling the filtered amplified difference signal.
