3. 17. Comparison between active and passive rectification for different types of permanent magnet synchronous machines

   University essay from Uppsala universitet/Elektricitetslära

   Author : Johannes Örnkloo; [2018]
   Keywords : PMSG; PMSM; rectification; saliency; converter; wind power;

   Abstract : When using an intermittent source of energy such as wind power together with a synchronous machine a frequency converter system is needed to decouple the generator from the grid, due to the fluctuations in wind speed resulting in fluctuating electrical frequency. The aim of this master's thesis is to investigate how different types of rectification methods affect permanent magnet synchronous machines of different saliency ratios. READ MORE
