Whakataki oKaitahuri
He taputapu hiko te kaitahuri e huri ana i te iahiko whakawhiti ki te iahiko tika, e whakamahia ana hei tuku hiko ki te kawenga. He taputapu te kaitahuri e huri ana i te pūtake ngaohiko DC ki te pūtake ngaohiko AC. Ka taea te whakamahi i roto i te rorohiko iti, i te pūnaha rorohiko iti maramara kotahi rānei, tae atu ki ngā taputapu tukatuka tohu.
Ngā kaitahuriKa taea te wehewehe i ngā kaitahuri kotahi-wāhanga, toru-wāhanga me te piriti-katoa i runga i te taumata mana. Ko ngā kaitahuri kotahi-wāhanga me toru-wāhanga he mea tito mai i ngā kaitahuri, ngā tātari me ngā tātari LC, ā, ko te ngaru putanga he ngaru sine; ko ngā kaitahuri piriti-katoa he mea tito mai i te ara iahiko tātari whakatikatika, te ara iahiko Schottky diode (PWM) me te ara iahiko taraiwa, ā, ko te ngaru putanga he ngaru tapawhā.
Ngā kaitahurika taea te whakarōpū kia toru ngā momo: te momo whakakā-whakaweto pumau, te momo whakahaere rohe-mate (ara ngaru sine) me te momo whakahaere pana (ara ngaru tapawhā). I te whanaketanga o te hangarau hikohiko mana, kua whānuitia te whakamahinga o ngā kaitahuri i roto i ngā mara maha.
Ngā ariā taketake
He taputapu hiko hiko te kaitahuri e huri ana i te iahiko tika ki te iahiko tauutuutu. Kei roto i te kaitahuri he ara iahiko tātari whakatikatika, he ara iahiko diode Schottky (SOK) me te ara iahiko taraiwa.
Ka taea te wehewehe i te inverter ki te inverter hohe me te inverter kore mahi, te inverter kore mahi, e mohiotia ana ko te ara iahiko inverter, te ara iahiko regulator ngaohiko rānei, ko te tikanga he wāhanga tāuru, he wāhanga takawaenga (LC) tātari, he wāhanga putanga (whakatikatika), me ētahi atu, ā, ko te inverter hohe te whakawhiti tohu ngaohiko tāuru ki te whiwhi i te ngaohiko DC pumau.
Ko te inverter korekore he pūnga utu kei roto i te piriti whakatikatika, ko te inverter hohe he inductor tātari kei roto i te piriti whakatikatika.
He iti te rahi, he māmā te taumaha, he tino pai te mahi, me ērā atu painga o te ara iahiko hurihuri. Koinei te wāhanga matua o ngā momo taputapu hiko mana katoa.
Whakarōpūtanga
E ai ki te āhua o te inverter, ka taea te wehewehe ki: te inverter piriti-katoa, te inverter pana-tōia.
Ka taea te wehewehe ki te inverter PWM (pulse width modulation), te inverter SPWM (quadrature signal modulation) me te inverter SVPWM (space voltage vector modulation).
E ai ki te momo ara iahiko taraiwa, ka taea te wehewehe ki: te momo haurua-piriti, te momo pana-tō.
E ai ki te momo kawenga, ka taea te wehewehe ki te pūhiko hiko hurihuri kotahi-wāhanga, te pūhiko hiko hurihuri toru-wāhanga, te kaitahuri DC, te pūhiko hiko hurihuri tātari hohe, me ētahi atu.
E ai ki te aratau whakahaere ka taea te wehewehe ki: te aratau iahiko me te aratau ngaohiko.
Mara tono
He whānuitia te whakamahinga o ngā kaitahuri i roto i te aunoatanga ahumahi, ngā taputapu hōia, te rererangi me ētahi atu mara. Hei tauira, i roto i te aunoatanga ahumahi, ka taea e ngā taputapu utu mana tauhohe e whakamahia ana i roto i ngā pūnaha mana te whakarite i te tuku hiko ngaohiko teitei, te whakapai ake i te pai o te whakaputa, te penapena i te hiko me te whakarato i te tuku hiko pumau mō te whakaputa ahumahi; i roto i te whakawhitiwhiti kōrero, ka taea te whakamahi i ngā taputapu utu mana tauhohe hei whakarite i te ngaohiko o ngā pūnaha ngaohiko iti hei whakau i a rātou i roto i te whānuitanga whaitake me te whakatutuki i te whakawhitiwhiti kōrero tawhiti; i roto i te kawe waka, ka taea te whakamahi i roto i te pūnaha tīmatanga miihini motuka me te pūnaha utu pākahiko motuka; i roto i ngā taputapu hōia, ka taea te whakamahi i roto i te tuku hiko me te pūnaha whakahaere aunoa o ngā taputapu patu; i roto i te rererangi, ka taea te whakamahi i roto i te tuku hiko tīmatanga miihini rererangi me te tuku hiko utu pākahiko.
