FPGA implementation of configurable three-Phase SPWM module

The work presented in this note concerns designing and implementation of a three phase SPWM reconfigurable module for power inverters to drive induction machines. In this paper we emphasise on reconfigurabilty of the SPWM characteristics such as modulation index, carrier frequency, modulating signal frequency and dead-time. The resulting vhdl code is simulated first using Quartus II software of Altera. Simulation and experimental results on DE2 cyclone FPGA are presented to verify the performance of this module.
