| Abstract |
The transformer causes a high amount of the overall losses in modern traction drives when operated withlow grid frequency. Besides the increased harmonics, an enhanced transformer with lower losses andthe same size increases the amplitude of the fault current significantly. A hybrid multilevel convertercan reduce the short-circuit current considerably with the internal capacitor voltages. Together with theenhanced output spectrum, the short-circuit current reduction enables the presented hybrid multilevelconverter to be used along with a transformer with reduced leakage inductance. |
