FPGA Implementation of SVPWM Technique for Seven-Phase VSI

This paper presents the performance investigation of FPGA implementation of SVPWM technique for seven-phase voltage source inverter (VSI). Seven-phase voltage source inverters are dominantly used to supply the seven-phase drives which are used for high power applications. In the SVPWM technique a large space vectors are detailed. A voltage source inverter with the proposed SVPWM is simulated in Matlab/Simulink. The performance of the 7-phase VSI is analyzed in terms of fundamental voltage and THD. In the proposed work, SVPWM algorithm is described in high-speed integrated circuit hardware description language coding and implemented in an XILINX Spartan 3A FPGA processor. The selection of zero and active space vector sequence are discussed and the possibilities of realization on FPGA are analyzed. 
