Nowadays, with the demand of high speed traction applications, for example traditional locomotive or Electric Multiple Units, medium-voltage high power AC drives are required. In the high power AC drives, the switch frequency of the devices has to be limited in order to reduce the loss of the power semiconductor devices. The modulation strategy is made up of asynchronous modulation, synchronous modulation...
A new space vector modulation (SVM) technique having a full and independent control of the multiple voltage space vectors of a six-phase voltage source inverter is presented in this paper. The proposed space vector approach is based on three-phase decomposition, leading to the modulation of two three-phase VSIs. The six-phase load consists in a dual three-phase induction motor, with insulated neutral...
