| Abstract |
Multilevel power converter technology is a recent alternative that address high power medium voltage applications requirements. This paper surveys the most popular topologies and modulation strategies used in multilevel power conversion, focussing on a novel Triphase Cascaded (TC) VSI that uses three standard triphase IGBT PWM inverter modules along with an 0.33 p.u. output transformer. A comparative analyse in terms of rating and complexity is carried out for the most common multilevel topologies with reference to the GTO Current Source Inverters (CSI). Computer simulations using SABER as well as practical experiments analyze the characteristics of this new topology in a typical medium-voltage adjustable speed drive (ASD). |
