| Abstract: | This paper first introduces topology of nine-level cascaded H-bridge inverter and two common modulation methods of it: Phase shifted modulation and voltage shifted modulation,then emphasizes the voltage simulation,and simulates it by Matlab/Simulink/Powersytem software,and at last carries concrete test by test devices.It is verified that the analysis in this paper is correct and the CHB inverter applied to the fields of high-voltage variable-frequency and(FACTS) of power system,etc.,has a high practical values. |
| Keywords: | Voltage shifted modulation cascaded H-bridge harmonic distortion. |
