Maximum Power Point Tracking of Direct-Drive PMSG with High-Efficiency Boost Converter
This chapter describes the variable speed stand-alone wind power supply system that incorporates permanent magnet synchronous generator, three-phase diode rectifier, and improved dc–dc boost converter with resistive load. Improved dc–dc boost converter controls to concentrate the most extreme power from the accessible wind. In the wind generation system, the power converter efficiency is one of the important considerations realizing the system performance. In those systems, dc-dc step-up converter is broadly utilized for high-conversion system. Considering the converter’s expense and efficiency, this chapter mostly concentrates on the outline of an enhanced topology of the boost converter received for high-power stand-alone wind power system. It describes the perturbation and observation maximum power point tracking algorithm. The MPPT algorithm in addition to the dc–dc step-up converter is simulated by MATLAB/Simulink software. The outcomes demonstrate that the dc–dc converter topology can understand the most extreme power point tracking control of the wind turbine.
