Zusammenfassung: | In this study, the aim is to evaluate three-phase (3
φ
) three-level (3L) neutral point clamped AC/DC rectifier for high-power applications. The rectifier analysis has been simulated using a new modified carrier-based level-shifted PWM technique. The 3L-NPC rectifier, which uses the new level-shifted PWM technique, is compared with the classical triangular carrier-based PWM signal. This new PWM technique provides low output voltage ripple, low total harmonic distortion (THD) for input current, unit input power factor, a well-regulated DC bus voltage and capacitor voltage balance for the NPC rectifier which is considered for implementation in high-power applications. This proposed modified carrier-based PWM is highly successful for 3L-NPC rectifier which is rated from 75 to 350 kW power applications. The system simulation results demonstrate the validity and flexibility of the proposed new carrier-based level-shifted PWM method for NPC rectifier in high-power applications. |
