The working principle of one-to-two ukuchithwa kwesithando somlilo

Imowudi yokusebenza ithatha enye ukuya kwezimbini, enye ukuya kwezimbini ithetha ukuba isethi yombane wokulungisa iqhuba ukusebenza kweeseti ezimbini zezixhobo ze-inverter.

Sebenza ngokuzimeleyo kunye naluphi na iseti yesixhobo sokuguqula i-inverter, unikeze amandla kwisithando somlilo A okanye isithando somlilo B, kunye nokunikezelwa kwamandla amabini kunye nomnye kwimisebenzi emibini, ngakumbi.

Ilungele ukwenziwa komsebenzi omkhulu oqhubekayo wemveliso encinci kunye nobungakanani obuphakathi, nasiphi na isithando sombane esinyibilikisa amandla aphezulu, esinye isithando somlilo.

Umzimba unokugcinwa ushushu okanye izinto ezibandayo zinokufudunyezwa kwangaphambili, kwaye amandla anokwabiwa ngokungekho mthethweni ngokweemfuno. Amandla apheleleyo amaziko ombane amabini ahlala rhoqo.

Oko kukuthi, amandla ewonke P ewonke = PA + PB

Ezi ziko zombane zimbini ziyanyibilika ngokuqhubekayo kwaye zihlale zishushu ukuze zifakwe ngelixa zisebenza ngaxeshanye, ukuze unikezelo lwamandla luhlale lusebenza ngamandla apheleleyo.

Kulungile, ukwenzela ukuba kuphuculwe imveliso yokunyibilika kwesithando sombane, umfanekiso ubonisa isithando sokunyibilikisa esinye ukuya kwezimbini.

Xa unikezelo lombane loguqulo lusebenza, isilungisi sihlala sisebenza ngokuqhutywa ngokupheleleyo, sitshintsha amandla okuphuma kweluphu yoguqulo.

Ifumaneka ngokulawula ukuphindaphinda kwe-inverter trigger pulse. Kwaye umthwalo wangoku uliza le-sine, ngoko ke unikezelo lwamandla ombane luqhagamshelwe kuthotho

Akuyi kubakho ii-harmonics ezikumgangatho ophezulu ezingcolisa ngokunzulu igridi yamandla, kwaye into yamandla iphezulu. Ii-inverters ezinxuseneyo azinakufikelela kwi-one-to- two self

Ukusebenza kohlengahlengiso lwamandla aguqukayo, kuba uhlengahlengiso lwamandla ombane ohambelanayo woguqulo lunokufezekiswa kuphela ngokulungelelanisa umbane wokuphuma kwebhulorho yokulungisa.

Xa ibhulorho yokulungisa i-inverter isebenza kwi-voltage ephantsi kwaye i-angle yokuqhuba yokuhlaziya incinci kakhulu, amandla esixhobo aya kuba sezantsi kakhulu.

Kwaye i-parallel inverter load current yi-square wave, eya kungcolisa kakhulu igridi. Ukuba amandla ahlengahlengiswa ngokulungelelanisa i-angle yoxinzelelo lwe-inverter ngasemva,

Uluhlu lohlengahlengiso lwamandla lumxinwa kakhulu, ngoko ke izixhobo zombane ze-inverter ezihambelanayo azikwazi ukufikelela kwi-one-drive-two operation.
