?MAXIMUM POWER POINT TRACKING

The efficiency of a solar cell is very low. In order to increase the efficiency, methods are to be undertaken to match the source and load properly. One such method is the maximum power point tracking.

This is a technique used to obtain the maximum possible power from a varying source. In photovoltaic systems the i-v curve is non-linear, thereby making it difficult to be used to power a certain load.

This is done by utilizing a boost converter whose duty cycle is varied by using a maximum power point tracking algorithm. Few of the many algorithms are listed below. A boost converter is used on the load side and a solar panel is used to power this converter.

Other function of maximum power point tracking controller is match the source and load / battery properly to deliver maximum power to load / battery.

Maximum power point tracking(maximum power point tracking) is a technique that grid connected inverters, solar battery chargers and similar devices use to get the maximum possible power from one or more photovoltaic modules.

Photovoltaic solar cells have a complex relationship between solar irradiance(w/square meter), temperature & total resistance that produces a non-linear output efficiency which can be analyzed based on the v-i curve.

It is the purpose of the maximum power point tracking system to sample the output of the to obtain maximum power for any given environmental conditions pv cells and apply the proper resistive load.
