Te kaupapa ara iahiko rama o te motuka
Kei roto i te ara iahiko rama o te motuka he pana, he aho, he fiusi, he whakawhiti me ētahi atu wāhanga, he whakawhiti mana fiusi o te iahiko nui, he whakawhiti mana pana o te iahiko iti, tēnā koa, he mana fiusi kei roto i tēnei iahiko iti? Homai he whakamārama motuhake. Ngā mihi.
Ka tohaina e au te pūrongo hei whakautu
Ko ēhea ngā mate pukupuku ka tūpono ka tukuna ki te whakatipuranga e whai ake nei?
He nui ngā mōhiohio e pā ana ki te pūtaiao me te hangarau mātauranga o nāianei
· He matatau ki te pūtaiao me te hangarau, ki ngā hangarau e pā ana ki te pūngao hou, me te rangahau hītori me te ahurea.
Arotahi ki
E whakaatu ana te pikitia i te ara iahiko whakahaere rama mua o te motuka. Kei roto i te kaiwhakahaere he ara iahiko whakaroa pumau kotahi (IC1, Rl, R2, RD, C1), he maha ngā wiri (IC2, R3, R4, C2), he ara iahiko whakahaere ngaohiko whakauru IC3(7812), he ngongo taraiwa hiko V-MOS BG2, BG3 me ētahi atu, e taraiwa ana i ngā rama mua e rua o te motuka.
Ka whakakahangia te pūmana e te pākahiko motuka +24V, ā, ka tukuna he ngaohiko DC o VDD=+12V mō IC1 me IC2 i muri i te whakahaerenga ngaohiko e IC3. Ina kore te taha o mua e neke ana i te ahunga kotahi, ka teitei te ātete whakaahua RD nā te mea kāore e kitea e te mārama, ā, ka tautuhia anō te IC1 e rite ana nā te taumata teitei o te waewae me te taumata iti o te waewae.
