A new modulation method is proposed to solve the unbalancing problem of neutral-point potential in the DC side in three-level (3L) three-phase neutral-point-clamped (NPC) voltage source inverters. Based on properties of current balancing of three phases and redundant short vectors, different short vectors have different time distribution factors, which

ABSTRACT In three‐phase two‐level inverters, the virtual space vector modulation (VSVM) has attracted widespread attention due to its ability to reduce the amplitude of common‐mode voltage and third harmonics. However, there are still problems such as rich harmonic components of common‐mode voltage and a high rate of occurrence of ...

In This paper, a direct torque control (DTC) method for bearingless permanent magnet synchronous motor (BPMSM) based on three-level neutral-point clamped (NPC) inverter is described. Through the analysis of virtual space vector modulation, an independent control strategy is adopted into the suspension winding control and a flux linkage error vector SVM-

Multiport dc-ac converter has gained attention due to its power density and low cost. However, in virtual space vector pulse width modulation (VSVPWM) where common-mode voltage (CMV) reduction and power control are considered, there are multiple switching actions in a period, which can be called multiswitch-VSVPWM (MS-VSVPWM).

The paper puts forth a novel idea for the computation of Nearest Three Virtual Space Vector Pulse Width Modulation for the three level NPC converters. The computations are based on the concept of final element shape function widely used in the domain of finite element analysis.

This paper proposes a space vector modulation based on the virtual AC/DC/AC conversion method for a matrix converter to reduce the switching loss. The switching loss of the matrix converter is not decided by only the number of switching times but also depending on the voltage and current in the selected switching devices based on the modulation.
