To increase the extraction power of a wind power system, the system must work at peak power. This paper presents maximum power extraction and control systems using a modified perturb and observe algorithm (MP&O) to achieve high efficiency maximum power extraction of wind turbines that connected to permanent magnet synchronous generators (PMSG). To get maximum power from PMSG, MP&O controls the duty cycle of synchronous buck based on the output power of the 12 pulses rectifier. The simulation results show that MP&O can work optimally at every change of wind speed. MP&O was also tested and compared with simple P&O in terms of ripples under stable conditions, response speed and ability to obtain maximum energy output. The average efficiency and convergence time achieved by MP&O are 99. 24% and 0. 71s.
