Power zvitengeswa - ayo akasiyana uye kushandisa

Mumwe mukuru matambudziko anotarisana nevanhu iyi ruzivo uye ruzivo afunge pamusoro zvemagetsi uye redhiyo namano, ndiro simba. Zvaidiwa mashoko uye vakatanga zano zvakadai sesimba mungabva (SP).

Pakusarudza mudziyo akadaro anofanira kufunga zvinoverengeka zvinokosha zvinoita, izvo takatsunga kubudikidza anodawo ezvinhu, kuchengeteka zvinodiwa, zvivako uye netsapo zvimwe zvinhu. Uyezve, tinofanira kufungawo mhando mano zvakadai, dzakadai mains romugove - kunogona simba, svikiro simba kana micropower.

Chokutanga unofanira kuteerera zvaidiwa parameters ari mudziyo zvinodiwa Powered mudziyo. Simba zvitengeswa ine vamwe vanoverengeka zvakafanana zvatariswa vanoronga: kuparadzwa razvino, voltage, simba inodiwa (kuipa kana chezita) sandara kudzikamisa voltage, zvinobvumidzwa (kwayo zvishoma uye kunonyanyisa ukoshi), padanho voltage ripple.

Uyewo, simba nerubatsiro ane zvimwe unhu uye unhu chokuita huchishanda uye chiyero. Somuenzaniso, kuvapo kana kusavapo yokudzivirira, uremu uye kukura mudziyo.

Power zvitengeswa - chinhu chinokosha chero wemagetsi. Zvinoreva zvose nesekondari simba wedzerai kuita zvakakodzera chaizvo zvinoenderana yaidiwa nzira dzinoshanda zvavo kuti midziyo yaro zvinoriumba nhengo. Kana akadaro zano sesimba bhuku, zvimwe zvokusarudza achauya mukati chikuva, izvozvo zvinogona kuita kuti kusawirirana chigadzirwa chayo hwakanaka.

Pane maonero akawanda samambure simba zvinyorwa:

- pamwe condenser, kana damping resistor (anonzi transformerless);

- Linear, izvo akaronga maererano dzekare zano (transformator- rectifier, zvichiteverwa filtration uye Kudzikamiswa);

- mukuru-voltage uye yakakwirira-Frequency kufamba kweropa;

- yechipiri kupomba (transformer redunhu uchishanda panguva yakakwirira frequencies filters - convert);

- mira-oga simba zvitengeswa;

- Linear Fe.

Linear ndicho nyore uye kutenga hobbyists. Ivo inowanzoshandiswa duku kadikidiki mano, zvakadai ndiro, mabhatiri, simba wedzerai hurongwa, zvichikurukura, uye zvichingodaro. Uyewo pano zvinogona kunzi kunobva risina kumiswa simba nerubatsiro (kupota).

Zvisinei, kana kushandisa magetsi netsika kupfuura rimwe ampere, kubudirira mudziyo yakadai, somunhu Linear simba nerubatsiro riri zvikuru kuderedzwa nezvikonzero zvakasiyana-siyana:

- Kudzikamiswa chinhu achava kusagadzikana nokuda oscillations ari mains voltage;

- matunhu dzenzvimbo zvinoda kugadzwa guru heatsinks pamusoro yokudzora transistors uye kugadzirisa diode;

- on stabilizer chiyamuro vachaguta zvakajeka yepamusoro voltage kupfuura kushanda pamwe nokufamba mukati pemambure.

Zvisinei, munguva pfupi yapfuura, yava zvakajairika mazuva kupomba converters (yechipiri), uyewo simba rine pahwaro mukuru maitikiro transducers pamwe transformerless zvinoshandisa pakurima.
