Ubonelelo Power - iintlobo zalo kunye nokusetyenziswa

Enye yeengxaki ezinkulu ezijongene zombini bathandi ezinamava kunye makhwelo nokuyila zonke izixhobo zombane kunye nonomathotholo, amandla. Iimfuno data yaye liphuhlise isixhobo ezifana njengomthombo wamandla (SP).

Xa ukhetha sixhobo kufuneka ithathele ingqalelo inani lemiba kubalulekile, nto leyo zigqitywa iimeko zokusebenza, iimfuno zokhuseleko, iimpawu kunye imithwalo nezinye izinto. Ngaphezu koko, kufuneka ukuba uyithathele ingqalelo iindidi izixhobo ezifana, ezifana unikezelo mbane - kunokuba ube namandla, igunya eliphakathi okanye micropower.

Okokuqala eyinhloko kuwe kufuneka ukuba uhlawule ingqalelo kokungqinelana parameters iimfuno device lwefowni ngamandla. Umbane sele inani elithile iimpawu ezifanayo isicwangciso: ukusetyenziswa lwangoku, ombane, inqanaba lamandla efunekayo (eqhelekileyo okanye ukulinganisa) ukuze uzinzise ombane, avumelekile (kunye nobuncinane yalo kunye nexabiso elikhulu), inqanaba yama- ombane.

Kwakhona, umbane ezinye iimpawu kunye neempawu ezichaphazela ngqo umsebenzi wayo kunye nesiqulatho. Umzekelo, ubukho okanye ukungabikho wokhuseleko, ubunzima kunye nemilinganiselo ifowuni.

ubonelelo Power - kuyinxalenye yentlanganisela nasiphi na isixhobo se-elektroniki. Kuthethwa zombini umbane yaseprayimari neyasesekondari Nifanele kuyimfuneko ukuba athobele imiqathango efunekayo ezisebenza jikelele nezixhobo nezibilini zayo candelo. Ukuba isixhobo esinjalo njengomthombo wamandla, ezinye iinketho ziya kuza ngaphakathi kuluhlu, oko kunokukhokelela nokungavisisani kwimveliso kunye nomonakalo yayo.

Kukho iimbono ezininzi imithombo yamandla yenethiwekhi:

- kunye ekondensa, okanye resistor damping (ebizwa ngokuba yi-transformerless);

- linear, leyo zicwangciswe ngokungqinelana kwesikim classical (rectifier transformator-, kulandele ukuhluza kunye nokuzinziswa);

- eliphezulu-ombane kunye aphezulu-rhoqo ukubetha;

- (yokusebenza circuit transformer ezitsho eliphezulu Amacebo okucoca - converter) naphakamileyo ukubetha;

- stand-alone unikezelo amandla;

- linear FE.

Linear yeyona ilula kakhulu nefikelelekayo kumntu bama. Ngokufuthi zisetyenziswa izixhobo ezincinane-ertyisi, ezifana iitshaja, iibhetri, amandla iinkqubo zokuzisa, kweesiginali, njalo-njalo. Kwakhona apha kunganxulunyaniswa umthombo umbane liqhawuke (UPS).

Noko ke, xa usebenzisa iimpawu zangoku ze ampere ngaphezu kwesinye, ukusebenza isixhobo esinjalo, njengokuba umbane yomgama i kabukhali kuncitshiswa yezizathu ezininzi:

- Ukuzinziswa factor uya kuba iyahlozinga ngenxa oscillations le ombane mbane;

- imisinga eliphezulu zifuna ukufakelwa heatsinks enkulu elawula transistors kunye ekulungiseni diode;

- kwigalelo somfanekiso ziya kondliwa ngokucacileyo ombane ngaphezulu kunayo nayiphi na esebenzayo kunye ukuhla kwi network.

Kutshanje, Noko ke, kubonakala ukuba converters ngendlela eqhelekileyo ukubetha (eziziisekondari), kwakunye njengomthombo wamandla ngokusekelwe transducers ophezulu kumaza amagalelo transformerless.
