abstract
The generation of non-characteristic harmonics in the AC supply feeding adjustable speed drives is experimentally investigated, taking into account the effect of the modulation index, the DC filter cutoff frequency and the output frequency. Test performed included a single ASD connected to the mains, two inverters connected to the DC link and two ASD%27s connected to the grid, all under balanced supply. The behavior with an unbalanced supply is also reported.
