Kufanya kazi
kanuni ya kazi ya ahf: ct ya nje hutambua sasa ya mzigo, dsp kama cpu ina hesabu ya juu ya udhibiti wa mantiki, inaweza kufuatilia kwa haraka sasa ya mafundisho, kugawanya mzigo wa sasa katika nguvu inayotumika na nguvu tendaji kwa kutumia fft yenye akili, na kukokotoa maudhui ya harmonic kwa haraka na kwa usahihi. kisha hutuma ishara ya pwm kwa bodi ya dereva ya igbt ya ndani ili kudhibiti igbt kuwasha na kuzima kwa masafa ya 20khz. hatimaye, inazalisha sasa fidia ya awamu ya kinyume kwenye uingizaji wa inverter, wakati huo huo ct pia hutambua maoni ya sasa ya pato na hasi huenda kwa dsp. kisha dsp inaendelea kwa udhibiti unaofuata wa kimantiki ili kufikia mfumo sahihi na thabiti zaidi.
