N2 - In permanent magnet synchronous generator (PMSG) based wind turbines, the back-to-back connected voltage source converter (VSC) can be replaced by a power converter based on diode rectifier, boost converter, and a grid tied VSC to decrease the cost and improve reliability. To accomplish fixed switching frequency operation, a deadbeat current control (DBCC) for the boost converter and a modulated model predictive current control (MMPCC) for the grid tied VSC is proposed in this paper. The DBCC regulates the inductor current for the maximum power point tracking, while the MMPCC controls the stationary-frame grid currents such that the grid active and reactive powers are regulated with excellent power quality. The proposed control method ensures less steady-state error, fast transient response and fixed switching frequency under a wide dynamic range. The simulation studies are conducted on a 750-kW direct driven surface-mounted PMSG wind turbine at different wind speeds and reactive powers to verify the feasibility of the proposed control method.
