Nyob zoo, Kuv ua qhov khoom siv hluav taws xob yooj yim no, raws li kuv xav tau +5V thiab -5V rau lub zog ua haujlwm ua haujlwm siab.
Lub tswv yim qub yog siv 78xx/79xx tsev neeg tswj hwm vim lawv yooj yim siv. Lawv tsuas muaj peb tus pin thiab tsis tas yuav muaj cov khoom siv sab nraud. Kuv tau siv LM371 rau +5V khoom thiab 7905 rau cov khoom tsis zoo. Kev siv LM371 nrog qhov sib txawv ntawm qhov sib txawv ua rau koj hloov pauv ntawm kev tswj hwm qhov khoom siv zoo kom sib npaug (hauv qhov muaj txiaj ntsig tsis tseeb) rau qhov tsis zoo, uas yog tsau.
Cov khoom siv hluav taws xob no yog ib feem ntawm qhov haujlwm loj Arduino. Kuv yuav ntxiv qhov txuas mus rau cov theem hauv qab no tom qab.
Kauj ruam 1: Simulation
Kuv tau ua qhov simulation nrog CUQS (Ubuntu raws) tsuas yog txhawm rau txheeb xyuas tias lub tshuab hluav taws xob siv yuav ua rau qis qis heev. Kuv siv 1, 000uF los lim cov zis ntawm diodes, thiab tshawb xyuas tias lawv raug.
Hauv CUQS software Kuv tau siv ob qhov AC los sim ua kom pom qhov tawm ntawm qhov chaw kaw qhov hloov pauv.
Kauj ruam 2: Cov ntaub ntawv
Nov yog cov npe ntawm cov khoom kuv tau siv los tsim cov khoom siv:
- 01 x hloov pauv 9V+9V nruab nrab kais
- 04 x rectifier diodes 1N4001 lossis sib npaug
- 02 x 1, 000uF electrostatic capacitor
- 01 x LM7905 peb lub davhlau ya nyob twg tsis zoo tswj qhov hluav taws xob
- 01 x LM317T kho qhov ntsuas qhov ntsuas hluav taws xob
- 01 x 1k resistor 1/8W lossis 1/4W (R3)
- 01 x 10k trimmer lossis potentiometer (R4)
Sau tseg: Hauv kuv cov ntaub ntawv hloov pauv yog 220V mus rau 9+9V nruab nrab kais, tab sis nws tuaj yeem yog qhov hluav taws xob, nruab nrab kais. Koj yuav tsum txheeb xyuas kom tsis pub tshaj qhov siab tshaj qhov hluav taws xob rau ob tus tswj hwm, LM7905 thiab LM317T. Koj tuaj yeem pom cov ntaub ntawv teev tseg ntawm cov khoom no yooj yim heev hauv Is Taws Nem.
Kauj Ruam 3: Schematics
Ntawm no yog schematic ntawm Circuit Court. Nws yog qhov yooj yim heev thiab tuaj yeem hloov kho rau lwm qhov hluav taws xob uas koj xav tau. Koj tuaj yeem siv 7908 lossis 7912 los ua +8V/-8V lossis +12V/-12V cov khoom siv fais fab. Nco ntsoov xyuas qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob kom ntseeg tau tias nws ua tau raws li qhov tshwj xeeb ntawm cov ntsuas hluav taws xob.
Kauj Ruam 4: Mounting Cheebtsam
Kuv mount tag nrho cov khoom siv hauv kab txaij. Kuv tawm ntawm qhov chaw rau txoj haujlwm tom ntej, uas tau teeb tsa thiab txuas lub tshuab ua haujlwm zoo. Koj tuaj yeem siv cov ntawv luam tawm uas koj xav tau. Koj tseem tuaj yeem siv daim ntawv qhia zaub mov rau kev tiv thaiv kab mob. Kuv siv peb tus pin txuas rau tus hloov pauv. Kuv tsis tau siv lub txuas rau qhov hluav taws xob tso tawm. Yog tias koj qhov haujlwm tsuas yog lub hwj chim muab, Kuv pom zoo kom koj muab lub txuas rau qhov tso tawm. Kuv tsis muaj qhov xav tau vim kuv yuav nce txhua yam ntawm lub rooj tsavxwm.
