Simba rekushandisa rine maitiro ehuwandu hudiki, kushanda kwepamusoro, kushanda kwakagadzikana uye kuvimbika kwepamusoro.Iyo magetsi ine yekuisa pasi-voltage, kubuda ikozvino kudzikamisa, kubuda pfupi circuit uye zvichingodaro.Iyo synchronous rectifier circuit inovandudza zvakanyanya kushanda kwesimba rekupa uye inochengetedza kushandiswa kwesimba.Iyo magetsi inopihwa yakafara voltage kupinza, yakafara ambient tembiricha, ine simbafactor correction circuit, uye ine huwandu hwakawanda hwemaapplication.
