FPGA-based SVPWM trigger generator for a 3/spl phi/ voltage source inverter

An FPGA-based space vector pulse width modulator (SVPWM) for use with a voltage source inverter is designed. The modulator is based on the comparison between the reference sinusoidal signals and a triangular carrier waveform. The carrier-based modulation is interpreted in terms of space vector theory. The design permits implementation of predefined modulation strategies and a user-designed strategy. The modulation configuration has been written in Verilog HDL code and typical modulator output pulses for different strategies have been presented.
