The output characteristics of photovoltaic arrays are nonlinear and change with the cell's temperature and solar radiation. Maximum power point tracking (MPPT) methods are used to maximize the PV array output power by tracking continuously the maximum power point (MPP). Among all MPPT methods existing in the literature, perturb and observe (P&O) is the(More)
This paper develops a pulse width modulation dc–dc non-isolated buck converter with the three-state switching cell, included by two diodes two active switches, and two coupled inductors. Only the load power is developed by the active switches, mitigating the peak current by the switches to 50 percentage of the load current, as much power levels can then be(More)
