The high efficiency IM drive by GTO CSI with regenerative commutation and snubber energy

Last updated on 20 September 2013 3:39

When operating the GTO CSI, the storage energy in dc link inductor and the leakage inductance of induction motor decreases the efficiency of CSI system, and switching devices are stressed by spike voltage generated at commutation time. Recently, the study is steadily progressed to develop these problems, such as GTO...
