Ugesi oshintshayo we-12v uwukusebenzisa izisetshenziswa zokushintsha zikagesi (njengama-transistors, ama-transistors omphumela wenkundla, ama-thyristors, njll.) ukwenza izisetshenziswa zokushintsha ze-elekthronikhi “zivuleke” futhi “zicime” ngokuqhubekayo ngokusebenzisa isifunda sokulawula, ukuze izisetshenziswa zokushintshwa zikagesi ziPulse. ukuguqulwa kwe-modulation kwenziwa ku-voltage yokufaka ukuze kubonakale ukuguqulwa kwamandla kagesi e-DC/AC, DC/DC, kanye ne-voltage ephumayo elungisekayo kanye nokulawulwa kwamandla kagesi okuzenzakalelayo.
Ukunikezwa kwamandla okushintshwa kwe-12v ngokuvamile kunezindlela ezintathu zokusebenza: imvamisa, imodi emisiwe yobubanzi be-pulse, imvamisa ehleliwe, imodi eguquguqukayo yobubanzi be-pulse, imvamisa, imodi eguquguqukayo yobubanzi be-pulse.Imodi yokusebenza yangaphambili isetshenziselwa kakhulu ukunikezwa kwamandla kagesi we-DC/AC, noma ukuguqulwa kwamandla kagesi e-DC/DC;izindlela ezimbili zokugcina zisetshenziswa kakhulu ekushintsheni ukunikezwa kwamandla okulawulwayo.Ngaphezu kwalokho, i-voltage ephumayo ye-switching power supply nayo inezinhlobo ezintathu zokusebenza: imodi ye-voltage ephumayo eqondile, imodi ye-voltage emaphakathi yokuphumayo, kanye nemodi ye-voltage ephumayo ye-amplitude.Ngokufanayo, imodi yokusebenza yangaphambili isetshenziswa kakhulu ekunikezeni amandla kagesi we-DC/AC, noma ukuguqulwa kwamandla kagesi e-DC/DC;izindlela ezimbili zokugcina zisetshenziswa kakhulu ekushintsheni ukunikezwa kwamandla okulawulwayo.
Ngokwendlela amadivaysi okushintsha axhumeke ngayo kusekethe, amandla okushintsha asetshenziswa kabanzi angahlukaniswa ngezigaba ezintathu: uchungechunge lokushintshwa kwamandla, ukunikezwa kwamandla okushintshaniswa okuhambisanayo, kanye nokunikezwa kwamandla okushintsha i-transformer.Phakathi kwazo, ukunikezwa kwamandla okushintshwa kwe-transformer (ngemuva kwalokhu okubizwa ngokuthi ukunikezwa kwamandla okushintshwa kwe-transformer) kungabuye kuhlukaniswe: uhlobo lwe-push-pull, uhlobo lwe-half-bridge, uhlobo lwebhuloho eligcwele, njll.;ngokusho kwe-excitation ye-transformer kanye nesigaba se-voltage okukhiphayo, ingahlukaniswa ngokuqhubekayo ibe: uhlobo lwe-excitation yangaphambili , i-flyback, i-excitation eyodwa kanye ne-double-excitation, njll;uma ihlukaniswa ukusetshenziswa, ingahlukaniswa ngezinhlobo eziningi.
Ngezansi sizokwethula kafushane izimiso zokusebenza zezinto ezintathu eziyisisekelo zokushintsha amandla, njengochungechunge, i-parallel, ne-transformer.Ezinye izinhlobo zokushintshwa kwamandla nazo zizohlaziywa ngokuningiliziwe isinyathelo ngesinyathelo.
