The paper proposes a computationally efficient finite state model based current control of a three-level neutral point clamped (NPC) five-phase voltage source inverter. The space vector model of a five-phase voltage source inverter (VSI) yields 243 space vectors, with 240 active and three zero vectors. The presented technique utilizes a modified switching algorithm to reduce the computation time while...
Conversion from variable ac voltage into fixed voltage and fixed frequency ac voltage is essential especially in case of grid-connected wind generation system. Direct matrix Converter (DMC) provides a solution for such ac/ac conversion for desired voltage and frequency. Five to three phase matrix converter developed in this paper is proposed to convert five-phase input voltage into three-phase voltage,...
The paper proposes model based current control of a five-phase voltage source inverter considering a finite set of control actions. The space vector model of a five-phase voltage source inverter (VSI) yields 32 vectors, with 30 active and two zero vectors. The presented technique utilizes 11 space vectors for the current control and hence the name finite control set is given. Search is made by the...
