Ko te supply mana (12 V) ki ona ringa ake. Te mana supply ara iahiko wae 12 wae

ka tukua supply Power supply mana 12 wae mo tata tetahi taputapu whare, tae atu ki ara he pona. Me mōhio e te pona he ngaohiko tāuru ki te 19 volts. Engari ka mahi i te reira pai noa, ki te mau koe i te horoinga o 12. Heoi, i te nāianei mōrahi o te 10 Amps. Anake ki taua uara mai kohi rawa uaua, i pupuri i te toharite e i 2-4 Amps. Kotahi te mea ki te whakaaro - ki te whakakapinga paerewa supply mana ki te whakamahi i te kāinga-hanga hanga-i roto i te pūhiko e kore e mahi. Tonu, te supply te mana ki te 12 volts he pai, ara mo te pūrere taua.

tawhā supply Power

Ko te tawhā tino nui o tetahi supply mana - te reira putanga ngaohiko me te nāianei. whakawhirinaki ratou uara i runga i tetahi - i te waea whakamahia i roto i te tuarua awhiowhio o te hiko. No te pārongo i runga i te āhua o ki te whakahaere kōwhiringa ka kōrero reira he iti i muri mai. Hoki ahau, E koe ki te whakatau i roto i mua i te whakaaro mo e whakamahere koe ki te whakamahi i te supply mana o 12 volts. Ki te hiahia koe ki te kaha i te taputapu mana-iti - kaiwhakatere, LED, a pera i runga, he reira rawaka ki te putanga 2-3 Amps. A ka waiho te rota tenei.

Otiia, ki te whakamahere koe ki te whakamahi i te reira ki te kawe i roto i ngā mahi ake nui - hei tauira, ki te ako atu i te pūhiko o te motokā, ka hiahia koe ki te puta 6-8 Amps. kia tekau nga wa iti iho i te kaha o te pūhiko ka tohutohutia nāianei - me tango tenei titauraa ki pūkete. Ki te kahore he he hiahia ki te hono i te whakaaro, te ngaohiko supply ko tino rerekē i te wae 12 i, ko reira tika ki te whakaturia te whakarerekētanga.

Me pēhea te ki te whiriwhiri i te hiko

Ko te huānga tuatahi - he pūtahuri ngaohiko. tauturu hiko ki taui i te ngaohiko AC o 220 volts ki te kaha tīwera taua, engari he nui iti te uara. I te tino iti rawa, e hiahia ana koe he uara iti. Hoki wae mana-tiketike rite te pūtake e taea te tango tatou i te hiko TS-270. He kaha nui, ara i reira e 4 kopiko, e take hoki 6.3 volts ia. whakamahia ratou ngongo mārua mō whakawera kai. Ngāwari i roto o taua mea, ka taea e hanga e koe te supply mana 12 wae 12 Amp, e taea ara atu tenei te pākahiko o te motokā.

Otiia ki te kahore e koe tino makona ki tona awhiowhio te, ko reira taea ki te tango Tuarua katoa, mahue te whatunga anake. A ki te pupuri i nga waea awhiowhio te. Ko te raruraru ko te pehea, ki te tātai i te maha e hiahiatia o hohoko. Hoki tenei e taea e tatou e te whakamahi i te kaupapa tātai ohie - tatau te maha o kopiko Kei roto te tuarua awhiowhio te e hua 6.3 volts. Na tika wehe 6.3 i te maha o hohoko. Na whiwhi koe i te uara ngaohiko, e taea te nekehia atu ki te koropiko kotahi o te waea. tonu te reira anake ki te tātai te nui e hiahia ana koe ki te hau i te coils ki te tiki putanga 12.5-13 volts. e riro te reira ara pai, ki te ka te putanga i 1-2 volts runga ake i te ngaohiko e hiahiatia ana.

rectifier production

He aha te mea he rectifier, a he aha te mea te reira hoki? hāngai ana tēnei pūrere te i runga i te p Semiconductor, i te mea he transducer. Ki reira, he nāianei tauutuutu te tahuri ki a DC. Hoki tātaritanga o te atamira rectifier mā te whakamahi i te tīkorikori mārama. Ki te kite koe i roto i mua o te sinusoid te p muri ka waiho ia ratou aho tata flat. Engari ka tonu noho nga mongamonga iti o te ngaru aho. Kia muri Peia atu o ratou.

Na roto i te kōwhiringa o te p kia tangohia ki te kaumatua whakamutunga. Ki te whakamahia te supply te mana ki te 12 volts te rite te zaryadchika pūhiko, ki te hiahia te whakamahi i ngā huānga nei whakamuri nāianei uara ki te 10 amperes. Ki te hiahia tatou ki te kawe i roto i iti-ngaohiko supply mana o kiritaki, ko reira nui ka hanga i te piriti. Here utu te mutu. Ko te tino hiahia ki te ara iahiko rectifier, kohia e momo piriti - wha p. Ki te tono tatou i te taua Semiconductor (taiawhio hawhe-poipoi), heke te tōtika te mana supply e tata te hawhe.

whakaminenga kōwae tātari

Na, ka kua he ngaohiko DC te putanga, he mea e tika ana e te hoahoa poraka o i paku pai ake te mana o te 12 volts. Hoki tenei whakaaro ko reira tika ki te whakamahi i ngā tātari. Hei kaha te taputapu te kāinga ki te whakamahi i LC-mekameka nui. I te mea te reira e tika ana ki te korero ki taipitopito atu. Ki te putanga pai o te atamira rectifier hono te hiko - kātere. Me tika te nāianei i roto i reira, ko te wā filtration tuatahi tenei. Next mai te tuarua - he pūnga -hiko ki te kaha nui (e rave rahi mano microfarads).

I muri te hono te piere ki te pūnga -hiko pai. Ko tōna putanga tuarua hono ki whenua (tango). Ko te ngako o te pūnga -hiko ko e taea ai te reira ki a koe kia whakakahoretia o te wae katoa AC. Kia mahara, i te putanga o te rectifier i nga wahi iti o te ngaru aho? Here, he mea e tika ana ki te pehea e o reira, ka pokanoa te mana supply 12 wae 12 Amp ki te whakaaro hono ki reira ranei. Hei tauira, te reo irirangi te reo irirangi ranei ka emit te buzz kaha.

Stabilization o te ngaohiko whakaputa

Hoki te stabilization o te ngaohiko whakaputa taea te whakamahi i anake kotahi huānga Semiconductor. Ka taea e waiho he ngōhiko ki te ngaohiko mahi o te 12 volts, me te ake momo huihui hou, me te mātanga LM317, LM7812 tenei. Tata hangaia mō te ngaohiko stabilization i 12 volts. Na reira, ara i raro i te huru e te putanga rectifier atamira 15 volts muri stabilization ka kia 12. anake te toenga haere ki wera. Tenei te tikanga e he reira faufaa ki te tāuta i te stabilizer i runga i te whakamahana.

ngaohiko waeture 0-12 V

Hoki rehe nui o te pūrere kia whakamahi i te ara iahiko ohie e taea te hanga i roto i te meneti torutoru. Ka taea te whakatinana i tēnei i te tikanga o te whakaminenga LM317 whakahuatia i mua. Anake te rerekētanga i te stabilization aratau whakawhitinga ara iahiko ko te iti. Ko te mea kiano i matao i roto i te waea, e haere ki haunga te, whakawhiti ārai tāupe 5 ohms. I waenganui i te whakaminenga putanga me te ātete ārai tāupe ngā o e pā ana ki 220 ohms. He i waenganui i kōkuhu me te whakaputa o te stabilizer whakataka tiaki ngaohiko - te ngōhiko Semiconductor. Ko te kupu, ko te supply te mana o te 12 volts, nga ringa kohia, tahuri ki pūrere multifunction. Na ka takoto ko ia anake ki te hanga i tona huihui, me te whakatika o te tauine. A ka taea e koe te mahi i putanga ki te hoatu i te ine ngaohiko hiko, i roto i nei, me te mataara ngaohiko o nāianei.
