Özet

The new three-phase 5-level current-source inverter (CSI) proposed in this paper was developed by connecting two classical current source inverters (CSIs) in cascade. This structure lend an output current harmonics minimization and without the use of high-frequency modulation. The output current waveform of the five-level CSI is composed of intermediary current levels, which are typically obtained from inductors current sources. The operational principle of this structure was analyzed. And to reduce the output current harmonics, triangular - sinusoidal PWM control technique was used. Simulation results showed that this new three-phase 5-level CSI topology operates correctly.
