Abstract :
The proposed study intends to investigate the benefits of using multilevel converters in low-voltage fed applications at high fundamental frequency as high-speed electric drives, with particular reference to the energy recovering from gas exhausts in automotive systems. Comparison of a conventional two-level sine wave converter and a neutral point clamped (NPC) converter has been developed and investigated. Experimental results have been achieved by means of a prototypal realisation of a three-phase three-level NPC converter.
