Ukushintshanisa ukunikezwa kwamandla kusekelwe kubuchwepheshe bokushintsha imvamisa ephezulu ukuze kuguqule amandla ashintshashintshayo angazinzile futhi axubene (AC) abe amandla kagesi aqondile aphansi (DC) adingwa amanye amadivayisi.Eqinisweni, ukunikezwa kwamandla okushintshwa kungashiwo ukuthi iyithuluzi elisizayo lenhliziyo leminye imishini, futhi umphumela walo mncane kakhulu.
Umqondo oyinhloko wokushintsha ukunikezwa kwamandla: ukwandisa amandla okunikezwa kwamandla ngokwezindlela ezifana nokukhulisa amandla okukhiphayo, ngaleyo ndlela unciphise usayizi nesisindo esiphelele se-transformer yamandla.Inzuzo enkulu yokuguqulwa kokuguqulwa kwamandla ukuthuthukisa ukusebenza kahle okuphezulu kokuguqulwa kwamandla kagesi.Ukusebenza kahle okuphezulu okujwayelekile kokunikezwa kwamandla e-PC kungu-70% -75%, kuyilapho ukusebenza kahle okuphezulu kwesilawuli sikagesi esihambisanayo sicishe sibe ngama-50%.
Ukuthembeka kwe-voltage ephumayo kusekushintsheni kobubanzi be-pulse, okubizwa ngokuthi i-pulse width modulation PWM.
Okuqukethwe okusebenzayo kokushintshwa kwamandla kagesi kulula.
Lapho ugesi wobunjiniyela bakamasipala ungena endaweni yamandla kagesi, imfuhlumfuhlu ephezulu kanye nokuphazamiseka kazibuthe kuyaqala kususwa ngokuya ngekhoyili yokuminyanisa kanye nedivayisi yokuhlunga ye-capacitor, bese kutholwa ugesi we-DC one-voltage ephezulu ngokuya ngesihlungi nesihlungi.Bese kuhlungwa ingxenye yokuxhumana kwe-high-frequency, ukuze ukunikezwa kwamandla kagesi we-DC okuhlanzekile okuhlanzekile kwemishini ehambisanayo kuphume ekugcineni.
