Design of an FPGA-Based 3-Phase SVPWM Controller

There are little torque ripple, low noise and high voltage utilization rate in SVPWM, which can obviously decrease inverter harmonic of output current and motor´s harmonic loss and pull down the torque ripple. Now SVPWM has been adopted in alternating current speed regulation system, but the generation of SVPWM is a difficulty during application. We design a three phases SVPWM controller with Xilinx FPGA XC3S400 SPARTEN3 based the fundamental principle of vector controlling and obtain a good result.
