Comparative Investigation on Integrated System of Permanent Magnet Synchronous Generator and Power Converter Based on Machine Topology for Small-Scale Wind Power Application

This paper presents the comparative analysis and test results of permanent magnet (PM) synchronous generators based on machine topology for small-scale wind power application. For reasonable comparison, various design considerations, such as flux direction, rotor position, slot existence and PM materials, are dealt with under specific machine size limitation. Among the analysis models, five machines are manufactured for experimental verification, and the generators are integrated with AC-DC-DC converter to convert originally generated AC power to DC power. With our constructed experimental set, the electromagnetic characteristics based on measured current, and their performance are comparatively investigated under constant output voltage control condition.
