Virtual Vector-Based FCS-MPC for NPC Three-Level Grid-Tied Inverter Without Weighting Factor of Neutral-Point Voltage Balancing
نویسندگان
چکیده
The neutral-point clamped (NPC) inverter is widely used in energy conversion, but the unbalance of voltage (NPV) will lead to imprecise control and decline power quality. Conventional finite set model predictive (FCS-MPC) uses an extra NPV weighing factor balance NPV. But weighting should tune frequently match best value. To cope with this problem, paper proposes a virtual vector-based strategy without for NPC inverters. analyses relationship between current voltage. An vector designed inject compensatory capacitor duration time each calculated from real-time Because balancing contains one vector, proposed method can cost function. Besides, function method. Finally, experiments are carried out verify validity

Zero-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 کاملA Varied VSVM Strategy for Balancing the Neutral-Point Voltage of DC-Link Capacitors in Three-Level NPC Converters
In the research field of multilevel converters, three-level NPC (neutral-point-clamped) converters, which unfortunately may cause the deviation of the neutral-point voltage of DC-link capacitors, are widely discussed. Theoretically, virtual space vector modulation (VSVM) could guarantee the balance control of the neutral-point voltage. However, there still exist some uncontrollable space vector...
