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 objective of this work is to design a controller circuit based on three-dimensional space vector modulation for a three-phase four-leg inverter. The implementation is performed on Zynq 7020 FPGA board using hardware description language (VHDL). XILINX FPGA provides a very attractive highlevel design/simulation tool called as Xilinx ISE; it is a very flexible tool, which allows testing of a highlevel structural description of the design and make possibilities for quick changes and corrections in the design
