This paper proposes a new virtual space vector modulation (VSVM) scheme that can eliminate the common-mode voltage (CMV) for three-level neutral-point clamped (NPC) inverters with balanced neutral-point voltage. The proposed VSVM scheme is based on the virtual space vector concept, which constructs the virtual vectors from the original medium vectors to achieve zero CMV. Moreover, the neutral-point...
This paper presents a novel space vector modulation (SVM) method combined with a modified four-step commutation to achieve a perfect zero common-mode voltage (CMV) for matrix converters (MCs). The new SVM method was developed by using only rotating input voltage vectors, which results in the CMV for MCs being zero. However, it causes some noise in practical applications that drive MCs with traditional...
This paper proposes a three-vector modulation (TVM) scheme for a five-leg indirect matrix converter (IMC) fed a three-phase open-end load (OEL) to control both rectifier and inverter stages with zero common-mode voltage (CMV) and low output current distortion. In order to reduce the CMVs at the load terminals and to eliminate the CMV across the load phases, three nearest active vectors are selected...
This paper presents a new space vector modulation (SVM) method for a three-phase five-leg indirect matrix converter (IMC) to drive a three-phase open-end winding load. The inverter stage of the new IMC topology is composed of five legs instead of the conventional six legs for the three-phase open-end winding load applications. The SVM method to drive the five-leg IMC is developed to operate the inverter...
This paper presents an alternative direct space vector modulation (DSVM) method of matrix converter for a voltage transfer ratio less than 0.5. The principles of selecting suitable switching configurations based on a new sectors definition are described. Switching table for the alternative DSVM method is developed with the controllable input power factor. There are some advantages of the alternative...
Currently, most of researches on matrix converter concerns about indirect rotor flux oriented control (FOC) method use MC indirect space vector modulation (SVM) technique. This paper introduces a direct rotor flux oriented control method using MC fed induction motor with the direct space vector modulation technique. Furthermore, the proposed technique of common-mode voltage reduction in direct space...
