Hei whakatutuki i te whakahaere tere rerekē o te motuka, he whānuitia te whakamahinga o te hangarau inverter i roto i ngā motuka ātete-pahū. Hei taputapu, ka taea e te inverter te huri i te pūtake hiko auau (50Hz, 60Hz rānei) ki roto i ngā momo pūtake hiko AC auau, kia tutuki ai te whakahaere tere rerekē o te motuka. Kei roto i te taputapu he ara iahiko whakahaere hei whakahaere i te ara iahiko matua; he ara iahiko whakatikatika hei huri i te iahiko whakawhiti ki te iahiko tika; ka whakamahia te ara iahiko waenga DC hei whakangawari me te tātari i te putanga o te ara iahiko whakatikatika; he ara iahiko inverter, hei huri i te iahiko tika ki te iahiko whakawhiti. I roto i ētahi kaitahuri auau e hiahia ana ki te mahi i te maha o ngā mahi, me whakauru hoki he CPU hei tatau i te taipana me te ara iahiko e rite ana. Mā te huri i te auau pūtake hiko o te takai stator o te motuka, ka taea e te whakahaere tere auau rerekē te whakatutuki i te kaupapa o te whakahaere tere.
Kaitahuri E ai ki ngā tikanga whakarōpū rerekē, ka taea te wehewehe ki te kaitahuri momo ngaohiko me te kaitahuri momo iahiko, te kaitahuri whakahaere PAM, te kaitahuri whakahaere PWM me te kaitahuri whakahaere PWM auau kawe teitei, te kaitahuri whakahaere V/f, te kaitahuri whakahaere auau paheke me te kaitahuri whakahaere whārite, te kaitahuri whānui, te kaitahuri motuhake mahi teitei, te kaitahuri auau teitei, te kaitahuri wāhanga kotahi me te kaitahuri wāhanga toru, me ētahi atu.
I roto i te kaitahuri auau, ko te VVVF e pā ana ki te ngaohiko me te auau e rerekē ana, ko te CVCF ia e pā ana ki te ngaohiko pumau me te auau pumau. I roto i te pūhiko AC e whakamahia ana i ngā whenua o te ao, ahakoa i roto i ngā kāinga, i ngā wheketere rānei, ko te ngaohiko me te auau he 400V/50Hz, 200V/60Hz rānei (50Hz). Ko te taputapu e huri ana i taua pūhiko ki te pūhiko AC taurangi ngaohiko, auau rānei ka kiia he "kaitahuri auau". Hei whakaputa i ngā ngaohiko me ngā auau taurangi, me huri tuatahi te taputapu i te iahiko whakawhiti ki te iahiko tika (DC).
Ka whakamahia te kaitahuri auau hei whakahaere i te motuka, ā, ka taea te whakarerekē i te ngaohiko me te auau. E ai ki te tere o te motuka AC, he rite te tere n ki te auau f, ā, ka taea te whakarerekē i te tere o te motuka mena ka whakarerekētia te auau f. Nō reira, ka whakatinanahia e te kaitahuri auau te whakahaere tere mā te whakarerekē i te auau o te tuku hiko motuka, he tikanga whakahaere tere tino pai, tino mahi hoki.
I te whanaketanga o ngā kaitahuri auau, he maha ngā tikanga whakahaere kua whanake, tae atu ki:
Aratau whakahaere whakapūtanga whānui pāoro sinusoidal (SPWM), ko 1U/f=C;
Aratau whakahaere i te vektara wāhi ngaohiko (SVPWM);
Aratau whakahaere whāka (VC);
Aratau whakahaere taipana tika (DTC);
Te whakawhitiwhitinga matihiko - te aratau whakahaere whakawhitiwhitinga, me ētahi atu.
Kei runga ake nei, ka whakamāramahia te whakamahinga auaha o te inverter i roto i te motuka ātete-pahū. Mā te hangarau inverter, ka taea te whakarite ngāwari i te tere o te motuka, ka kawea mai he otinga mana tino pai me te mahi teitei ki te mara ahumahi.
