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

Abstract

The four-leg inverter has been shown to be a solution for inverters operating in four-wire distribution systems. The technique three-dimensional space vector modulation (3DSVM) used is a reliable solution as it utilizes DC bus voltage more efficiently. The objective of this work is to design a controller circuit of 3DSVM for a three phase four-leg inverter. The implementation is done on Zynq 7000 FPGA board using hardware description language (VHDL). FPGA provides a very attractive high-level design/simulation tool called as Xilinx ISE; it is a very flexible tool, which allows testing of a high-level structural description of the design and make possibilities for quick changes and corrections in the design
