Abstract :
This paper presents a novel space-vector modulation strategy to implement and operate the novel zero-voltage transition (ZVT) three-phase inverter on electric vehicle driving systems. The proposed space-vector modulation (SVM) strategy allows all main switches to turn on with zero-voltage condition at any load condition, as well as keeps the benefits of the conventional SVM scheme which has four commutations in one switching cycle. The proposed ZVT topology implemented on an electric vehicle inverter reduces the cost and space for the auxiliary circuit compared to the ZVT topologies with six switches. The simulation and loss estimation shows the improved characteristics of the proposed SVM scheme and ZVT topology
