Nyob zoo sawv ntxov.

Qhov no yog hais txog kev hloov pauv (ib qho ntxiv) rau lub zog hluav taws xob muab los ntawm lub tshuab hluav taws xob.

Ua ntej tshaj plaws, dab tsi yog 'lub tshuab hluav taws xob tsheb tuam'? Nws yog lub tshuab hluav taws xob uas siv lub zog txav los ntawm lub log thiab cov kauj tsheb kauj vab; qhov tseeb, nws hloov lub zog ntawm koj ob txhais ceg mus rau lub zog hluav taws xob (pub dawb !!).

Nov yog qee qhov piv txwv:

Zoo tshaj plaws-DIY-Bike-Trainer-Generator

Qhov xav tau ntawm lub hauv paus ntawm tus qauv ntawm tus adapter no yog kom tau txais lub zog ntawm 5Vdc (rau cov neeg tso npe ntaus ntawv rov qab) thiab 12Vdc (rau teeb pom kev zoo, tshwj xeeb tshaj yog thaum lub tshuab hluav taws xob tau siv qhib cua: thaum lub caij ntuj no nov tsaus ntuj thaum ntxov …).

Kauj ruam 1: Schema Zuag qhia tag nrho

Nov yog tag nrho cov phiaj xwm ntawm lub adapter:

Los ntawm sab laug, lub tshuab hluav taws xob yog lub cav hlau nplaum tas mus li, khaws los ntawm kev tshem tawm kev teeb tsa;

Kauj ruam 2: Tus Generator

Hauv qhov no yog 3-theem txhuam lub cev tsis muaj zog, tab sis txhuam txhuam lub cev muaj zog kuj tseem yuav zoo: tsuas yog, yuav tsuas muaj 2 lub xov hlau hloov ntawm 3.

Thov nco tseg: Cov xov hlau liab yog qhov txuas 'lub hnub qub', Kuv tsis siv nws hauv txoj haujlwm no (xaim txuas tsis txuas).

Kauj Ruam 3: Kev Txhim Kho

Raws li tus kws kho mob, kuv tau siv 3-theem diode choj ua ke, khaws los ntawm qhov hloov pauv zaus; tau kawg nws tuaj yeem ua ib qho nrog 6 diodes txuas nrog hauv cov phiaj xwm. (rau DC txhuam lub cev muaj zog nrog 2 lub xov hlau, koj yuav xav tau tsuas yog 4 diodes, tom qab paub zoo 'Graetz choj' teeb tsa).

Lub tshuab hluav taws xob ua kom du yog siv ncaj qha rau ntawm qhov txuas ntawm lub diode choj, tsuas yog txhawm rau kom tsis txhob ntxiv 2 lub xov hlau ntxiv rau cov kab uas twb tsis meej …

Kauj Ruam 4: Rho Tawm Voltage

Kuv ntxiv lub ntsuas hluav taws xob, txhawm rau ua kom pom kev sib raug zoo ntawm qhov nrawm ntawm kev txav mus los thiab qhov hluav taws xob nro tau tsim.

Raws li kuv lub voltmeter yog lub vaj huam sib luag qub galvanometer nrog 100µA qhov kawg-ntawm-nplai (ntawm no kuj, khaws los ntawm qhov qub tshem tawm kev teeb tsa), Kuv ntxiv 500K lub zog ntsuas kom tau txais 40V qhov kawg-ntawm-teev (qhov xav tau tiag tiag tiv taus tus nqi txog 400K).

Vim li cas 40V? Vim tias DC-rau-DC hloov pauv tom qab tuaj yeem lees txais cov tswv yim ntawm 40V siab tshaj.

Yog lawm, yog tias koj lub tshuab xa hluav taws xob ntau dua, koj yuav tsum nrhiav DC-rau-DC hloov pauv uas tuaj yeem lees txais qhov hluav taws xob ntawd; Piv txwv li, yog tias koj lub tshuab hluav taws xob xa hluav taws xob nruab nrab ntawm 80V thiab 240V, tej zaum koj tuaj yeem siv lub phab ntsa-ntsaws rau lub khoos phis tawj nqa tau.

Thawj DC-DC hloov pauv (12V):

Kuv tau ua kuv tus kheej vim tias kuv tsis muaj ib qho uas muaj zog txaus (kwv yees li 6 amps) thiab npaj tau; ua nws, Kuv siv 34063A kev sib xyaw ua ke: nws muab 1A max, tab sis hauv nws Cov Ntawv Qhia (los ntawm ST.com lossis Addmtek.com cov vev xaib, piv txwv) koj yuav pom daim ntawv thov txheej txheem rau siab dua tam sim no, siv PNP sab nraud transistor (Kuv siv BDX54c). Txog qhov tsis pub dawb diode, Kuv tau siv 'Rov Qab Rov Qab' ob zaug diode khaws los ntawm lub qub Desktop PC lub zog muab khoom. Cov kauj yog xuas tes ua, nrog cov tooj liab txaus kom ua tiav 220 µH induction tus nqi, raws li qhia hauv Cov Ntawv Qhia.

Tom qab qhov kev hloov pauv DC-DC thawj zaug no, kuv tso Ampère-meter (hauv kab ntawv), txhawm rau tso saib lub zog siv los ntawm txhua lub cuab yeej koj tuaj yeem txuas (12V teeb, lub xov tooj them nyiaj, …); ib zaug ntxiv, qhov no tsis tsim nyog tab sis nws tuaj yeem muaj txiaj ntsig zoo rau txhua lub hom phiaj kev qhuab qhia thaum kawg.

Qhov 12Vdc nro tau txais yog siv los muab lub caij nplooj ntoo hlav txuas (ib yam li cov uas siv los txuas tus neeg hais lus rau lub zog qis hauv tsev Hi-Fi teeb tsa), txhawm rau ua kom 12V yooj yim rau siv tau; Kuv xav tias hauv kuv qhov xwm txheej nws yuav yog rau qhov hluav taws xob qis LED teeb pom kev zoo.

Kauj Ruam 5: 5V Cov Hluav Taws Xob

Kev nqes me ntsis ntxiv, qhov thib ob DC-DC hloov pauv kom tau txais 5Vdc cov zis; lub sijhawm no kuv tau ua ib qho lawm, khaws los ntawm lub tshuab luam ntawv cua sov qub.

Txhawm rau kom tau txais 5V cov khoom siv sab nrauv muaj, Kuv tau ua lub rooj tsav xwm yooj yim nrog qee qhov txuas USB; qhov no yog DIY, tab sis koj tuaj yeem khaws cia ib qho zoo sib xws los ntawm qee lub PC Desktop qub: feem ntau lawv muaj 2-, 4- lossis txawm tias 6- USB txuas hauv qab.

Kauj Ruam 6: Xeem

Cov duab kawg yog hais txog qhov kev xeem zaum kawg; Kuv siv lub zog 18Vdc, vim kev teeb tsa lub tsheb kauj vab tseem tsis tau paub (tseem).

Daim duab thib ob qhia txog 12Vdc qhov hluav taws xob, qhov kawg yog hais txog 5Vdc USB qhov hluav taws xob kuaj.

Kev txhim kho tom ntej:

Txog kev khaws lub zog, ntau txoj hauv kev tuaj yeem ua tau; piv txwv:

a) nrog 2 xov hlau, ua kom muaj nyob sab nraud ntawm qhov nrawm ntawm qhov kawg ntawm cov nplaim hluav taws xob; tom qab ntawd nws tuaj yeem tuaj yeem muab tus nqi tswj rau 12V cov roj teeb ua kua qaub (raws li siv rau tsheb).

b) txuas lub txhab nyiaj USB mus rau 5V USB qhov hluav taws xob.

Ua tsaug rau koj mloog, Kuv vam tias nws yuav yog ib qho txiaj ntsig.

Thiab, tau kawg, ua tsaug rau Lub Vev Xaib Qhia rau qhov no (pub dawb!)
