Design of SPWM inverter IP core based on SOPC
Based on FPGA and SOPC, IP core of pulse width modulation technique is studied in this paper. According to the principle of sinudoidal PWM by natural sampling, using VHDL and macro functions module design method, the design of PWM IP core on FPGA is achieved. Switching frequency and dead time are programmable. The functions of the IP core are simulated and tested. The results of simulation and experiment are shown.
