A maximum power point tracker (MPPT) for photovoltaic (PV) cells, PV modules (PVM) and PV arrays is presented using a dynamic optimal voltage estimator to estimate the voltage at which a PV cell generates its maximum power, and, using a DC-DC converter, to force the PV cell to reach and operate at voltage in a finite time and to stay there for all future time. The optimal voltage estimator reads the...
This paper describes a fixed maximum power point analog control used in a step-down pulse width modulated power converter. The DC/DC converter drives a DC motor used in small water pumping installations, without any electric storage device. The power supply is provided by PV panels working around their maximum power point, with a fixed operating voltage value. The control circuit implementation is...
