Me pēhea te whakamahi i te pūtahuri DC/DC?

I tēnei wā, he maha ngā momo kaitahuri DC/DC kei te mākete, ko te kaitahuri autō he momo āhuahanga kaitahuri DC/DC, mā te whakahaere i te auau whakawhiti hei whakatutuki i tētahi ara iahiko autō ngaohiko putanga pumau. E whakamahia whānuitia ana ngā kaitahuri autō i roto i ngā tono ngaohiko teitei hei whakangawari i ngā āhua ngaru, hei whakapai ake i te tauwehenga mana, me te whakaiti i ngā ngaronga whakawhiti i puta mai i ngā pana mana auau teitei pērā i te MOSFET me te IGBT. He mea nui kia mōhio ko te ara iahiko LLC e whakamahia whānuitia ana i roto i ngā kaitahuri autō nā te mea ka taea te whakawhiti ngaohiko kore (ZVS) me te whakawhiti iahiko kore (ZCS) i roto i te awhe whakahaere, ka tautoko i ngā auau whakawhiti teitei ake, ka whakaiti i te tapuwae o ngā wāhanga, ka whakaiti i te pokanoa hikohiko (EMI).

Te hoahoa hoahoa o te kaitahuri resonant

He mea hanga he kaitahuri autō i runga i tētahi kaitahuri autō e whakamahi ana i tētahi whatunga pana hei huri i te ngaohiko tāuru DC ki tētahi ngaru tapawhā, ka whakamahia ki tētahi ara iahiko autō. E ai ki te Pikitia 2, ko te ara iahiko autō he pūnga autō Cr, he inductor autō Lr me tētahi inductor autō Lm o te whakawhiti hiko i roto i te raupapa. Ka tātarihia e te ara iahiko LLC ngā harmonika teitei ake mā te mimiti i te mana mōrahi i tētahi auau autō ngaru tapawhā pumau me te tuku i te ngaohiko sinusoidal mā te autō autō. Ka whakanuia, ka whakaitihia rānei tēnei āhua ngaru AC e tētahi whakawhiti hiko, ka whakatikatikaina, kātahi ka tātarihia hei whakaputa i te ngaohiko putanga DC kua hurihia.

Kaitahuri DC/DC whakapūmau LLC Simplified

Ko te iahiko pūtake toharite tapawhā (RMS) o te pūnga tētahi o ngā tawhā nui hei whakaaroaro māu i te wā e whiriwhiri ana i tētahi pūnga Cr e tika ana mō tētahi kaitahuri DC/DC. Ka pā tēnei ki te pono o te pūnga, te ngaohiko e rere ana, me te mahi whānui o te kaitahuri (i runga i te āhua o te ara iahiko e rere ana). Ka pāngia hoki te mararatanga wera e te iahiko RMS me ētahi atu mate o roto.
