| Abstract: | Based on the analysis of power net harmonic detection and SPWM,a new active power filter system controlled both by DSP and PIC chip is designed.Power net information is first collected by signal acquisition circuit,with TMS320F2812' s high signal processing speed to detect harmonic wave and operate FFT algorithm, the calculated compensation circuit signal is transmitted to dsPIC30F4012 that can provide special three-phase protected and dead time included PWM output to drive inverter.It divides the control o... |
