Kwinkqubo yokulungiswa kwenkqubo ye-laser, sihlala sibona iparamitha ye-“PWM”, ngoko ke ithetha ukuthini, masiyijonge namhlanje.
I-PWM sisishunqulelo se-“Pulse Width Modulation”, ekubhekiselwa kuyo “njengomodareyitha yobubanzi be-pulse” okanye “ukumodareyitha”, bubuchule obusebenzayo kakhulu bokusebenzisa imveliso yedijithali ye-microprocessor ukulawula iisekethe ze-analog.
Imowudi yokuphuma kwelaser ikakhulu ibandakanya iintlobo ezimbini: imo eqhubekayo kunye nemodi ye-pulse.Imodi eqhubekayo kukudubula okuqhubekayo kweelaser;Imowudi ye-Pulse kukukhupha i-laser ngaxeshanye lonke elinye ixesha.Umzekelo olula, njengokukhanya kwe-flashlight: ukuvula iswitshi ayicinywanga yimo eqhubekayo;Ukuvula iswitshi ngoko nangoko kwaye emva koko ukuyicima kukukhupha i-pulse, kwaye inkqubo yokuvula nokucima ngokuphindaphindiweyo yindlela ye-pulse mode.Ngokufanayo, xa isibane sithatyathelwa indawo yilaser, imowudi yepulse kukuphinda inkqubo yokukhanyisa nokucima ukukhanya ngokuqhubekayo.
Eyona ndlela ithe ngqo yokuvelisa i-laser ye-pulsed kukongeza imodyuli kwi-CW laser ukulungelelanisa i-laser ye-CW ukufumana i-pulse output.I-PWM (I-Pulse Width Modulation) kukulungelelanisa ububanzi be-pulse ngokulungelelanisa umjikelo womsebenzi.
Xa ulungelelanisa iiparameters zenkqubo yokusika i-laser, i-pulses kunye ne-duty cycles zihlala zisetyenziswa, kwaye abaqhubi abaninzi abangaqhelananga nenkqubo yokusika i-laser banokungaqondi indima yezi parameters zimbini, kwaye ke bakunike isingeniso esicacileyo.
1Ixesha
Umqondiso usuka phezulu ukuya phantsi kwaye ubuyele phezulu kwixesha leveki enye
2Isantya se-Pulse frequency
Mingaphi imijikelo ye-PWM ekhoyo kwisekondi enye
3Umjikelo womsebenzi wePulse
Umzekelo womlinganiselo wexesha eliphakamileyo ukuya kwixesha lonke lomjikelo kumjikelo
4Pul ixesha kunye nexesha
Ixesha lexesha elithathwa kumjikelo
5Ububanzi be-Pulse
Ixesha lexesha elisetyenziselwa ixesha elithile kwizinga eliphezulu
6Incopho yesantya samandla
Imveliso yamandla ekhawulezileyo yelaser ngaphakathi kobubanzi bepulse enye
7Umyinge wezinga lomsebenzi
Ubungakanani bamandla aphuma kwilaser kumjikelo wokuphindaphinda
Ngesiqhelo, xa simodareyitha i-laser kwi-debugging yenkqubo ye-laser, amandla aphezulu, i-pulse frequency kunye nomjikelo womsebenzi usetiwe.Okulandelayo, makhe sisebenzise umzekelo ukubonisa indlela yokubala iiparamitha zePWM.
Kumandla aphezulu e-laser, umjikelezo womsebenzi we-pulse uyanda, kwaye amandla kwi-irradiation ye-pulse nganye iya kwanda ngokufanelekileyo, okuya kwandisa umthamo wokucubungula kwicala lobunzima beplate.Ukuba umjikelo womsebenzi we-pulse uyancitshiswa, amandla kwi-pulse nganye ayakhanyiswa, okunceda ukunciphisa ukugqithisa kunye nokulahlekelwa kwe-fusing.
Kwinkqubo yokwenziwa kwesinyithi, amandla e-laser asetyenziswa, kwaye kwimeko yamandla e-laser rhoqo, kokukhona i-frequency iphezulu, incinci imveliso yamandla ye-laser nganye, ngoko ke kufuneka simisele i-frequency efanelekileyo ngokwesantya sokusebenza. xa amandla e-laser anele ukunyibilikisa isinyithi.
I-laser ye-GW esekwe kwitekhnoloji yempompo ye-976nm yeemveliso ze-laser ze-fiber eqhubekayo, enobuchule obuphezulu be-electro-optical conversion, umgangatho olungileyo wokuphuma komqadi, ubuninzi bokumodareyitha ukuphindaphinda ukuya kuthi ga kwi-50kHz, esetyenziswa ngokubanzi ekusikeni, kwi-welding, ekucoceni, ekugqumeni nasekuveliseni okongeziweyo.
