FPGA based space vector modulated trigger controller for a frequency converter

Abstract

This paper proposes FPGA based space vector modulated (SVM) trigger controller that may be applied to a frequency converter used for high speed electrical drives, speed control of AC motor, induction heating, fluorescent lighting, ballast, high frequency power supplies and so on. To generate space vector pulse width modulated trigger pulses for the converter pperipheral input-output and FPGA interfacing has been developed through Xilinx 9.2i. In order to relieve the controller from the time consuming computational task of PWM signal generation, method of space vector PWM signal generation is implemented on FPGA using Hardware Description Language VHDL in Xilinx. Simulated results are shown on ISE-Simulator and they are found to be satisfactory.
