Isihluzi seHarmonic esisebenzayo (AHF)—Isigaba esinye
Isishwankathelo seMveliso:
Izihluzi ezisebenzayo ze-harmonic (AHF) zezona zisisombululo sigqibeleleyo kwiingxaki zomgangatho wamandla ezibangelwa kukuphazamiseka kwemo ye-waveform, amandla aphantsi, ukutshintsha kwe-voltage, ukuguquguquka kwe-voltage kunye nokungalingani komthwalo kuluhlu olubanzi lwamacandelo kunye nezicelo. Ziluhlobo lwezihluzi zamandla ezisebenzayo (i-APF) ezisebenzayo, ezincinci, eziguquguqukayo, eziguquguqukayo nezingabizi kakhulu ezibonelela ngempendulo ekhawulezileyo nesebenzayo kwiingxaki zomgangatho wamandla kwiinkqubo zamandla ombane eziphantsi okanye eziphezulu. Zivumela ubomi bezixhobo obude, ukuthembeka okuphezulu kwenkqubo, amandla kunye nokuzinza okuphuculweyo kwenkqubo yamandla, kunye nokulahlekelwa kwamandla okuncitshiswa, ukuthobela imigangatho yomgangatho wamandla kunye neekhowudi zegridi ezifunekayo.
Ii-AHF zisusa ukuphazamiseka kwe-waveform kwimithwalo efana neeharmonics, iiharmonics kunye ne-notching, kunye nee-voltages ze-harmonic ezibangelwa yi-harmonic currents, ngokufaka ngexesha langempela i-current ephosakeleyo yobukhulu obufanayo kodwa eyahlukileyo kwisigaba kwinkqubo yamandla ombane. Ukongeza, ii-AHF zinokunyamekela ezinye iingxaki ezininzi zomgangatho wamandla ngokudibanisa imisebenzi eyahlukeneyo kwisixhobo esinye.
Umgaqo Wokusebenza:
I-CT yangaphandle ibona umbane womthwalo, i-DSP njengoko i-CPU ine-logic control arithmetic ephucukileyo, inokulandelela ngokukhawuleza umbane womyalelo, yahlule umbane womthwalo ube ngamandla asebenzayo kunye namandla asebenzayo ngokusebenzisa i-FFT ekrelekrele, kwaye ibale umxholo we-harmonic ngokukhawuleza nangokuchanekileyo. Emva koko ithumela isignali ye-PWM kwibhodi yomqhubi ye-IGBT yangaphakathi ukulawula ukuvula nokucima i-IGBT kwi-frequency ye-20KHZ. Ekugqibeleni ivelisa umbane we-phase compensation ochaseneyo kwi-inverter induction, kwangaxeshanye i-CT ikwabona umbane we-output kwaye impendulo engalunganga iya kwi-DSP. Emva koko i-DSP iqhubeka nolawulo olulandelayo lwe-logical ukuze ifumane inkqubo echanekileyo nezinzileyo.
