PROJECT TITLE :
Analytical Evaluation of Surface-Mounted PMSG Performances Connected to a Diode Rectifier
This paper analyzes some operational problems of three-section surface-mounted permanent magnet synchronous generators (PMSGs) connected to a diode rectifier. This easy configuration coupled to one-switch dc–dc converter is employed in small-scale wind energy conversion systems, with in energy harvesting systems, to reduce prices. The diode rectifier causes an intrinsic limit for the maximum convertible power, that is related to the load impedance matching, and extra joule losses because of the distorted currents. By using an analytical steady-state model of the rectifier and of the PMSG, this paper discusses how to realize 2 notably meaningful operating conditions characterized respectively by the utmost power transfer and the utmost power per ampere. The theory is validated by simulation and check results on a prototype.
