I-LV AHF yokunciphisa i-Harmonics kwiNethiwekhi yoMbane

Ujongene nengxaki enkulu yongcoliseko lwe-harmonic yamandla, i-AHF sesona sixhobo sisebenzayo sokuphucula umgangatho wamandla. I-AHF sisixhobo esitsha esikhethekileyo solawulo lwe-harmonic yamandla ephuhliswe kusetyenziswa itekhnoloji yale mihla yombane we-elektroniki kunye neteknoloji yokusetyenzwa kwemiqondiso yedijithali esekwe kwizixhobo ezisebenza ngesantya esiphezulu zeDSP. I-AHF ilingana nejeneretha yangoku ye-harmonic, elandelela amacandelo e-harmonic kwi-harmonic current kwaye ivelise i-harmonic currents kunye ne-amplitude elinganayo kunye nesigaba esichaseneyo. Umyalelo wesekethe yokusebenza yangoku ibona i-current in the circuit ngexesha langempela, iguqula i-analog signal yangoku ibe yisignali yedijithali, kwaye iyithumele kwi-high-speed digital processor (DSP) yokulungiswa komqondiso. I-harmonic kunye ne-principal currents zihlukaniswe ukuze zifumane i-current instruction, ethi ke ithunyelwe kwimbuyekezo yesizukulwana sangoku sesiphaluka ngendlela ye-pulse wide modulation (PWM) isignali ngokusebenzisa isiphaluka solawulo lokulandelela umkhondo kunye nesekethe yokuqhuba. Iimodyuli zamandla e-IGBT kunye ne-IPM ziqhutyelwa ukuvelisa imbuyekezo yangoku kunye ne-amplitude efanayo kunye ne-polarity echaseneyo njenge-harmonic current, efakwe kwigridi yamandla ukuhlawula okanye ukukhansela i-harmonic current, ukuphelisa ngokusebenzayo i-harmonics yamandla, kunye nokufezekisa ukuqhutyelwa kwe-dynamics, ngokukhawuleza, kunye nokucokisekileyo kwe-harmonics yamandla.

iinkcukacha zemveliso

I-AHF ilungele imithwalo yomthamo ophezulu wemizi-mveliso, njengabahlaziyi, abaguquli bamaza, i-UPS enkulu, ii-arc furnaces, ii-intermediate frequency furnaces, iitshaja zezigaba ezithathu, kunye nezinye iimeko zomthwalo wamanqanaba amathathu. Ifanelekile kwimithwalo yesigaba esisodwa esingenasiphelo kwizakhiwo zorhwebo, njengezibane zokugcina amandla, iikhomputha, i-UPS, i-elevators, i-air conditioners eguquguqukayo, njl., Ezenza i-harmonic yesithathu kunye nokutshisa i-N-line.
