A new method of maximum power point tracking (MPPT) of photovoltaic (PV) cells using impedance adaption by Ripple correlation control (RCC).

In this paper , we are likely to introduce a new method of tracking maximumpower point of PV arrays . the relationship between arrays output power and load impedanceenables us to provide suitable adaption between load impedance and internal impedance ofarrays and find the optimum operating point to receive maximum available power of PVarrays . a boost convertor is connected between arrays and load to adapt load impedance toPV internal impedance . Ripple correlation control (RCC) , is used as a basic law to correlateload impedance and power Ripples in order to compute duty ratio of switching devices tomaximize PV output power via adapting load and PV internal impedance .
