To adapt to the new need and the quick development rhythm of the aero power quality,a modulation scheme of aero inverting circuit was designed by means of the advanced modern EDA technique and pulse-width modulation technique. The area-equivalent sine wave pulse width modulation(SPWM)was adopted to set up control mathematics model. The logic function needed in circuit design was realized with number operation,digital conversion and hardware description Language VHDL. PLDs are taken as the hardwares of the modulation control circuit. With the MAX+plus Ⅱ software,the simulation and hard-ware testing experiment were completed on the EDA test developing system(GW-GK system),the three-phase SPWM waveform pulse series was acquired,the digitaliztion control was realized,the wave harmonic component was decreased and the almost ideal sine wave was obtained. The method simplified the structure and scale of the control circuit,and increased the control ac-curacy and credibility of the system.
