Ukusuka kwingqikelelo yemoto, i-DC motor yimoto ye-DC eguqula amandla ombane e-DC abe ngamandla oomatshini, okanye ijenereyitha ye-DC eguqula amandla oomatshini abe ngamandla ombane e-DC;umatshini ojikelezayo wombane ophuma okanye igalelo lamandla ombane eDC ubizwa ngokuba yimoto ye-DC, eyi-eneji ye-A motor eqonda uguqulo oludibeneyo lwamandla ombane e-DC kunye namandla oomatshini.Xa isebenza njengemoto, yimoto yeDC, eguqula amandla ombane abe ngamandla oomatshini;xa isebenza njengejenereyitha, yijenereyitha yeDC, eguqula amandla oomatshini abe yi-DC amandla ombane.

Kwiimotor ezijikelezayo, ii-harmonic currents okanye i-harmonic voltages ziya kubangela ilahleko eyongezelelweyo kwi-stator windings, i-rotor circuits kunye ne-iron cores, okukhokelela ekunciphiseni ukuguqulwa kwamandla okusebenza ngokubanzi kwemoto.I-Harmonic yangoku inokonyusa ukusetyenziswa kobhedu lwemoto, ngoko ke phantsi komthwalo onzima we-harmonic, i-motor iya kuvelisa ukufudumeza kwasekhaya, ukonyusa ukungcangcazela kunye nengxolo, kunye nokunyusa ukunyuka kwamaqondo obushushu, okukhokelela ekugugeni okukhawulezileyo kwe-insulation layer kunye nokunciphisa ubomi besixhobo.Abanye abalandeli babuze, iinjini ze-AC ziya kuba neeharmonics, nokuba iimoto zeDC nazo zinale ngxaki?

Ubungakanani kunye nolwalathiso lwangoku olutshintshayo luya kutshintsha ngamaxesha kunye nexesha, kwaye ixabiso eliqhelekileyo elisebenzayo kumjikelo omnye ngu-zero, kwaye i-waveform idla ngokuba sinusoidal, ngelixa i-current ngqo ingatshintshi ngamaxesha.Ukutshintshana kwangoku sisiseko samagnetic, esenziwe ngoomatshini.Nawuphi na umsinga otshintshayo kufuneka ube neempawu ze-electromagnetic, kwaye kukho imathiriyeli engundoqo yemagnethi.Umsinga othe ngqo usekelwe kwikhemikhali, nokuba yi-photovoltaic okanye i-lead-asidi, ikakhulu iguqula amandla ekhemikhali kumandla ombane.

Ukuguqulwa kwe-alternating current ukuya kumbane othe ngqo kungokulungiswa kunye nokucoca ukufumana i-pulsating current ngqo.Umsinga othe ngqo uguqulwa ube ngumbane otshintshayo ngokujikeleza kunye nokuguqulwa, kwaye i-sine wave alternating currents ifunyenwe.

Izizathu eziphambili zokuvelisa i-harmonics ziquka ukuchithwa kwesiseko esisisiseko kunye nokuveliswa kwe-harmonics ngenxa ye-voltage ye-sinusoidal esetyenziswa kumthwalo ongekho.Imithwalo engundoqo engabonakaliyo yi-UPS, ukunikezelwa kwamandla okutshintsha, ukulungiswa kwakhona, i-frequency converter, i-inverter, njl.Isizathu se-harmonics ye-AC rectifier kunye nezixhobo zamandla ze-DC kukuba isixhobo sokuhlaziya sinombane wevalvu.Xa ingaphantsi kombane wevalve, okwangoku ngu-zero.

Ukuze unikeze umbane ozinzileyo we-DC wolu hlobo lwezixhobo zombane, izinto zokugcina amandla ezifana ne-filter capacitors kunye ne-inductors zokucoca zongezwa kwisixhobo sokuhlaziya ukunyusa umbane wevalve kunye nokuvuselela ukuveliswa kwee-harmonics.Ukuze kulawulwe i-voltage kunye ne-current ye-DC izixhobo zombane, i-thyristor isetyenziswa kwisixhobo sokulungisa, esenza ukuba ungcoliseko lwe-harmonic lwezixhobo ezinjalo lube lukhulu ngakumbi, kwaye umyalelo we-harmonic uphantsi.
