| Abstract |
Traditionally, multilevel converters are utilised in medium voltage applications, allowing the dc-link voltage to exceed the switch maximum blocking voltage. Here, their application to control high-efficiency brushless permanent magnet synchronous machines exhibiting low phase inductance is explored, the relative advantages being shown to include reduced current ripple and improved harmonic spectrum. A cost benefit analysis is included along with experimental results from a prototype 5-level back-to-back converter. |
