Implementation of four dimensional space vector modulation for five phase voltage source inverter

In this paper, a Four Dimensional Space Vector Modulation (4D-SVM) is implemented for five phase Voltage Source Inverter (VSI) to improve the performance of the inverter. The 4D-SVM control technique generates switching pulses for five phase VSI system. The reference vector for 4D-SVM is identified by tracking subcubes and prisms located in the complex 4D-cubic region. The 4D-SVM for five phase inverter includes 32 switching state vectors; all the switching states are non-redundant switching states, which are located in 32 vertices of the 4D-cube. The proposed five phase inverter with 4D-SVM reduces CMV and Total Harmonic Distortion (THD) and minimized neutral current value. The minimization of CMV leads to avoid the damage of the winding and increases the life time of the motor. So for in two level inverter, the CMV is reduced up to Vdc/3 times of input voltage; In this proposed system, made an attempt to reduce the CMV level below this reported value. The simulation and hardware results are verified using matlab simulink and Field Programmable Gate Array (FPGA) processor
