High performance current control techniques for applications to multilevel high power voltage source inverters

摘要: Several high-performance current-control techniques have been developed for applications to multilevel high-power voltage source inverters. The logical sequence of the design choices is described. They result in a very robust and reliable control system that allows an adequate switching optimization excellent dynamic responses. advantages using various accessible DC potentials fully exploited. results obtained by digital simulation refer five-level waveforms, but strategies can easily be applied any inverter structure, even case n-level waveforms. validity proposed schemes has confirmed both simulations tests carried out on scale models. >
