Implementation of space vector modulation for FPGA based frequency converter

Frequency converter may be used to control the speed of AC motors, in airline industries, induction heating, fluorescent lighting, ballast, high frequency power supplies and so on. It has a advantage of eliminating one or more intermediate converters. The use of self-commutated switches with PWM control can significantly improve the performance of frequency converter. This paper presents FPGA based space vector modulated (SVM) trigger controller applied to a frequency converter where trigger pulses are generated Hardware Description Language VHDL in Xilinx. The output waveforms have been synthesized for different value of output frequency. The trigger circuit has been tested qualitatively by observing various triggering pulses on Xilinx ISE simulator and then verified with experimental results. The operation of proposed system has been found satisfactory.
