Abstract This paper studies the power electronic converters for grid connection of axial flux per-
manent magnetic synchronous generators (AFPMSG) based variable speed wind turbine. In this
paper, a new variable speed wind turbine with AFPMSG and Z-source inverter is proposed to
improve number of switches and topology reliability. Besides, dynamic modeling of AFPMSG is
presented to analyze grid connection of the proposed topology. The Z-source inverter controls max-
imum power point tracking (MPPT) and delivering power to the grid. Therefore other DC–DC
chopper is not required to control the rectified output voltage of generator in view of MPPT. As
a result, the proposed topology requires less power electronic switches and the suggested system
is more reliable against short circuit. The ability of proposed energy conversion system with
AFPMSG is validated with simulation results and experimental results using PCI-1716 data acqui-
sition system.
