This study analyses a field programmable gate array (FPGA) implementation of space-vector pulse-width modulation (SVPWM) technique for five-phase voltage source inverter (VSI). The five-phase VSIs are dominantly used to supply the fivephase drives that are used for high-power applications. It is necessary to develop an appropriate SVPWM technique for the inverters to provide the required output voltages to five-phase induction motor load. In the proposed work, SVPWM algorithm is described in high-speed integrated circuit hardware description language coding and implemented in an XILINX XC3SD1800A FPGA processor. The relationship between the SVPWM technique for medium, large and combinations of large and medium space vectors for five-phase VSI is analysed. The selection of active space vector and zero vectors is discussed and the possibilities of FPGA implementations are explored. The experimental results with 1 hp five-phase induction motor drive are presented for the different SVPWM techniques. The best SVPWM scheme is identified based on the output voltage and total harmonic distortion.
