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.
