I-Pulse Rectifiers
I-Pulse rectifiers, eyaziwa ngokuba yi-pulsed rectifiers okanye i-rectifiers elawulwayo, zizixhobo eziguqula i-AC ukuya kwi-DC ngokusebenzisa izixhobo ezilawulwayo ze-semiconductor ezifana ne-thyristors okanye i-silicon-controlled rectifiers (SCRs). Ezi zihlaziyi ziqhele ukusetyenziswa kwizicelo ezifuna ulawulo oluchanekileyo kumbane ophumayo kunye nowangoku.
Umgaqo wokuSebenza
Ukusebenza kwe-pulse rectifier kubandakanya ukulawula i-angle yesigaba segalelo lombane we-AC. Ngokulungelelanisa i-angle yokuqalisa i-SCRs, i-voltage ye-DC ephumayo inokulawulwa. Xa i-SCR iqhutywe, ivumela i-current ukuba idlule kuze kube yilapho umjikelezo we-AC ufikelela kwi-zero, apho i-SCR ivala. Le nkqubo iphinda kumjikelo ngamnye wesiqingatha segalelo le-AC, ivelisa i-pulsating output ye-DC.
