FPGA based embedded implement of space vector pulse width modulation

This paper introduces the working principle of space vector pulse width modulation (SVPWM), and presents a new circuit realization of SVPWM generator based on FPGA-embedded technique. MicroBlaze is a 32-bit high-performance processor embedding in the FPGA chip, and the left logical units can be used to design IP cores that needed, thus software and hardware can be combined to realize this SVPWM control system. The proposed SVPWM control scheme can be realized using a single FPGA chip. This scheme contains the advantages of SVPWM generator and FPGA-embedded technique, thus being important for high performance control system, and a new way for the design of high-performance motion control systems is provided.
