Performance comparison of an alternative converter for wind powered switched relutance generators

Abstract

– The subject of this paper is a comparison of the performances of two converter topologies for Switched Reluctance Generators – SRG. It deals with this special electrical generator excited through a rectified DC link. The prime mover is a wind turbine. Mathematical model and simulation results are presented. Both the power converters topologies implemented work well but the alternative one is cheaper and more efficient than the conventional half-bridge one. Furthermore, only the alternative converter allows to feed the load from the grid even when the SRG is not running. This is good for complementary wind power. Experimental results are presented. It was shown that the SRG worked as expected and that the alternative topology reached expectations.
