Huang XiangSheng, Qun Wang · Advances in computer science research · 2015
A waveform circuit of SPWM based on SOPC is designed.In Quartus II 9. 0 environment, Using Verilog HDL and module design method the design is completed.The selected FPGA model is EP2C35F672C6 in Cyclone series.According to the principle of sinusoidal PWM by irregular sampling, using the real-time overlapping of sine wave and triangular wave, the periodic adjustable SPWM wave is achieved.The results of simulation show that SPWM generator IP core could be embedded in special processor, and realize the driving of SPWM components.
