| Popis: | This paper presents Space Vector Modulation (SVM) sequences that reduce Common-mode Voltage (CMV) in Dual Three-phase Asymmetrical Induction Motor (DTAIM). First, existing SVM techniques namely Standard SVM (SSVM) and CMV1 are studied and then, three new switching sequences CMV2, CMV3 and DCMV3 are proposed which reduce peak magnitude of CMV by 66.8% in comparison with SSVM technique. In SVM techniques, to obtain least CMV, zero vectors are usually replaced by two opposite large Active voltage Vectors (AVs) with equal time duration. In such topologies like CMV1, total six AVs are utilized to synthesize reference vector. The proposed CMV2 utilizes only five large AVs to synthesize reference vector and reduces CMV. Selection of five neighbouring AVs in proposed techniques yields reduction of harmonic flux trajectories and stator current ripple. Additionally, two more switching sequences (CMV3 and DCMV3) are developed that is related to utilization of specific zero voltage vectors in all sectors (7 and 56) and produce zero CMV. The CMV and stator current ripple are considered as performance parameters for different SVM techniques. All SVM techniques are analysed by analytical results, computer simulations, and using prototype test setup of DTAIM fed by Dual Three-phase Voltage Source Inverters (DTVSIs). |
