Nokuba ngaba ukhetha ulawulo lwesigaba-shift okanye ulawulo lwe-zero-crossing xa iumlawuli wamandlaiyasebenza kufuneka kugqitywe ngayo ngokwemeko yesicelo esithile.Ulawulo lwe-Zero-crossing lubhekiselele ekuvuleni isixhobo sokutshintsha isixhobo ngalo lonke ixesha amandla ombane ombane edlula kwindawo engu-zero, kunye nokulawula umbane womthwalo ngokulungelelanisa ubude bexesha lokuqhuba.Le ndlela yokulawula inesiphumo esingcono xa umthwalo uyisithintelo somgca, kwaye unokufikelela kumandla aphezulu.Ulawulo lwesigaba-shift lubhekiselele ekuvuleni isixhobo sokutshintsha isixhobo kwizigaba ezahlukeneyo zombane wombane, kunye nokulawula umbane womthwalo ngokulungelelanisa ubude bexesha lokuqhuba.Le ndlela yokulawula ifanelekile kwimeko apho umthwalo uyisithintelo esingenasiphelo (njengenkqubo yokulawula isantya se-motor), kwaye unokuqonda ukulungiswa okugudileyo kwe-voltage yomthwalo kunye nokhoyo, ukuphepha ukugqithiswa kunye nokunqunyulwa.Ngoko ke, nokuba ukhetha ukulawulwa kwe-phase-shift okanye i-zero-crossing control ngexesha lomsebenzi kufuneka kukhethwe ngokweyona meko.Ukuba umthwalo uyisithintelo somgca kwaye ufuna umbane ophezulu, ulawulo lwe-zero-crossing lunokukhethwa;ukuba umthwalo uyi-impedance engabonakaliyo, kwaye i-voltage yomthwalo kunye ne-current idinga ukulungiswa kakuhle, ulawulo lwe-phase-shift lunokukhethwa.
Kufuneka kuqatshelwe ukuba xa usebenzisa ulawulo lwe-zero-crossing, isixhobo sokutshintsha i-carrier kufuneka sihambelane ne-zero point ye-voltage yobonelelo lwamandla ukuphepha iingxaki ezifana nokuwela umbane kunye neencopho zangoku ezigqithisileyo.Ngoko ke, ngokuqhelekileyo kuyimfuneko ukusebenzisa i-trigger yongqamaniso oluzinikeleyo ukugqiba le nkqubo.
Khetha isigaba-shift okanye imowudi yokuwela zero xa ukhethascr umlawuli wamandlauninzi luxhomekeke kumthwalo wakho kunye nendlela iheater yakho eya kusebenza ngayo.Ukuba unombuzo malunga noku, qhagamshelana noNoker Electric ngokuthe ngqo, siya kukunika esona sisombululo.
