A rising number of people are interested in using a PV-Wind hybrid system. This hybrid system is found to perform better compared by using a single source system. Regarding to the non-linearity of the photovoltaic (PV) and wind source output, and the changing environmental circumstances, the hybrid system requires the usage of maximum power point tracking (MPPT) controller. Various MPPT techniques for PV-Wind hybrid systems have been reported in several articles during the last few years. This paper reviews several MPPT techniques that have been implemented in the existing PV-Wind hybrid system. Those MPPT techniques have been classified into three groups which are classical, artificial intelligent (AI) and bio-inspired. The principal operation, advantages, and disadvantages of a few techniques of each group has been discussed. Also, a MPPT structures, types of DC-DC converter, and performance of the MPPT are being presented.
