FPGA-based IC design for inverter with vector modulation technique

Abstract

Presents an application of a Xilinx FPGA device, in the CX4000 family, producing pulse width modulation (PWM) signals with the vector modulation technique for an IGBT inverter. Using a single FPGA chip for the practical implementation of the modulator, rather than a system consisting of microprocessor and external memory, has many advantages including less use of power and space, short design time, greater speed and reliability. The designed circuit can generate PWM signals, and also, the input values used to adjust output signal may be obtained through a microprocessor port. A comparison between the implementation on DSP and on FPGA at the level time will be made to validate the use of the FPGA.
