A New Generalized Space Vector Modulation Algorithm for Neutral-point-clamped Multilevel Converters
Neutral-point-clamped converters are increasingly applied in industrial drive systems as they allow the use of lower voltage devices in higher voltage applications, provide reduced output voltage total harmonic distortion(THD), and can develop low common mode voltage. Several distinct modulation strategies have been proposed in the past for eliminating the common mode voltage, providing low THD...
متن کاملModified Unipolar Carrier-Based PWM Strategy for Three-Level Neutral-Point-Clamped Voltage Source Inverters
This paper presents a simple modified unipolar carrier-based pulsewidth modulation (CBPWM) strategy for the three-level neutral-point-clamped (NPC) voltage source inverter (VSI). Analytical expressions for the relationship between modulation reference signals and output voltages are derived. The proposed modulation technique for the three-level NPC VSI includes the maximum and minimum of the th...
متن کاملZero-voltage switching for the neutral-point-clamped (NPC) inverter
This paper proposes a transformer-assisted pulsewidth-modulation zero-voltage-switching neutral-pointclamped (NPC) inverter. With the assistance of a transformer-assisted small-rating lossless auxiliary circuit, the main switches work with zero-voltage switching without suffering from any voltage/current spikes, under simple explicit control. The technique allows for higher operating frequency ...
متن کاملControl Strategy of Single-Phase Three Level Neutral Point Clamped Cascaded Rectifier
Single-phase 3-level neutral point clamped cascaded rectifier (3LNPC-CR) has been successfully made its way into traction drive system as a high-voltage traction converter. In this passage, the control issue of the 3LNPC-CR is considered. A transient current control strategy, combined with proportional integral (PI) controllers, is adopted to achieve unity power factor, satisfactory sinusoidal ...
متن کاملThirteen and Fifteen Level Neutral Point Clamped Multilevel Inverter
Multilevel inverters (MLI) becomes more accepted over the last few years in high power application of electrical engineering with the advantage of less disturbances and the possibility to work at lower switching frequencies as compared to conventional two-level inverters. In this paper the simulation of single phase multilevel inverter is present. Simulation of three level, five level, seven le...
