A new converter/inverter system for windpower generation utilizing a new 600 Amp, 1200 volt intelligent IGBT power module

This paper briefly reviews the need for windpower generation and the power quality issues associated with the utility interface. The design requirements for the system which drove the need for a new high power intelligent power module (IPM) are presented. The new IPM is described along with its key features and characteristics. The features and implementation of the generator and line side matrices are described. The operation of the IPM in the new system is described and its output along with the output waveforms of the line side inverter are shown. Switching waveforms from both pulse testing and full matrix operation are included to illustrate normal operating, short circuit, and over-current modes. Line side current waveforms demonstrate the effectiveness of the active line side filter in meeting the low total harmonic distortion requirements of the electric utility
