Design and implementation of three-dimensional space vector modulation for three-phase four-leg inverter based on FPGA

Abstract

The four-leg inverter presents a best topology for inverters operating in four-wire distribution systems. The goal of this work is to design circuit to control the three-phase four-leg inverter using three-dimensional space vector modulation. The implementation is performed on Zynq 7000 FPGA board based on hardware description language. XILINX FPGA presents a very high level fixable design/simulation tool named Xilinx ISE, which makes us able to test, change and correct the high level structural description design quickly.
