FPGA-Based Design and Implementation of Space Vector Modulation for Three- Phase Three-Level NPC Inverter

Abstract

In comparison with conventional two-level inverters, multilevel inverters present lower switching losses, lower voltage stress on switching devices, lower common-mode voltages and better harmonic performance. Due to these remarkable features, nowadays the application of this technology covers a wide range, where high-quality voltages and currents are required. This thesis presents an FPGA based implementation of space vector modulation for three-level diode clamped inverter. The three-level inverter using SVM control has superior performance though bringing about much computational complexity. Therefore, the XILINX Zynq 7000 FPGA-based implementation could solve this problem well.
