On the control of photovoltaic maximum power point tracker via output parameters

摘要: A new approach for tracking the maximum power point of photovoltaic arrays is presented. The tracker output voltage and current are used control purposes, rather than its input current. It shown that using parameters simplifies controller. Moreover, this approach, only one out two needs to be sensed. This observation general applies regardless stage or realisation algorithm. Contrary what might have previously been assumed, it theoretically MPPT uses a single parameter nearly all practical load types, nature.
