Photovoltaic inverter yog qhov tshwj xeeb inverter siv hauv thaj tsam ntawm hnub ci photovoltaic zog tsim. Nws tuaj yeem hloov pauv ncaj qha tam sim no tsim los ntawm cov hnub ci cell rau hloov pauv lub zog tam sim no uas tuaj yeem ncaj qha sib xyaw rau hauv daim phiaj thiab thauj los ntawm lub zog hluav taws xob hloov pauv thev naus laus zis. Nws yog qhov tseem ceeb hauv cov tshuab photovoltaic. Cov khoom tseem ceeb. Photovoltaic grid-txuas inverters, raws li cov cuab yeej siv sib txuas ntawm cov xov tooj hluav taws xob photovoltaic thiab daim phiaj, hloov hluav taws xob hluav taws xob ntawm cov xov tooj hluav taws xob photovoltaic mus rau qhov hloov pauv tam sim no thiab xa lawv mus rau kab sib chaws, ua lub luag haujlwm tseem ceeb hauv kev tsim hluav taws xob txuas hluav taws xob.
Lub inverter hloov ncaj qha tam sim no mus rau qhov hloov pauv tam sim no. Yog tias qhov hluav taws xob ncaj qha tam sim no qis, nws tau txhawb nqa los ntawm kev hloov pauv tam sim no kom tau txais tus qauv hloov pauv qhov hluav taws xob tam sim no thiab zaus. Rau qhov muaj peev xwm loj inverters, vim yog lub tsheb npav DC siab heev, AC feem ntau tsis xav tau lub tshuab hloov pauv kom txhawb qhov hluav taws xob kom mus txog 220V. Hauv nruab nrab thiab qhov muaj peev xwm me me inverters, vim qhov qis DC voltage, xws li 12V, 24V, Nws yog qhov tsim nyog los tsim lub zog txhawb zog.
Qhov nruab nrab thiab qhov muaj peev xwm me me inverters feem ntau suav nrog rub-rub inverter circuits, puv-choj inverter circuits thiab high-zaus boost inverter circuits. Push-rub circuits txuas nruab nrab ntsaws ntawm lub zog hloov pauv mus rau lub zog zoo, thiab ob lub raj xa hluav taws xob Hloov ua haujlwm, tso tawm AC zog, vim tias lub zog transistors txuas nrog rau hauv av, kev tsav tsheb thiab tswj kev sib txuas yog yooj yim, thiab vim tias lub tshuab hloov pauv muaj qee qhov xau inductance, nws tuaj yeem txwv qhov luv-Circuit tam sim no, yog li txhim kho kev ntseeg tau ntawm Circuit Court. Qhov tsis zoo yog qhov kev siv lub tshuab hloov pauv tau qis thiab lub peev xwm los tsav cov khoom siv hluav taws xob tsis zoo.
Tus choj puv inverter Circuit Court kov yeej qhov ua tsis tau ntawm lub laub-rub Circuit. Lub zog hluav taws xob hloov kho qhov tso zis dav dav, thiab qhov txiaj ntsig zoo ntawm cov zis AC voltage hloov pauv raws li. Vim tias lub vojvoog muaj lub voj voos freewheeling, txawm tias yog cov khoom siv inductive, qhov hluav taws xob qhov hluav taws xob tawm yuav tsis cuam tshuam. Qhov tsis zoo ntawm qhov kev sib tw no yog tias lub zog transistors ntawm sab caj npab thiab qis qis tsis sib koom hauv av, yog li yuav tsum siv lub zog tsav tshwj xeeb lossis cais cov khoom siv hluav taws xob cais. Ib qho ntxiv, txhawm rau tiv thaiv kev sib koom ua ke ntawm cov caj npab sab saud thiab qis dua, yuav tsum tsim lub kaw lus kom kaw thiab tom qab ntawd qhib, uas yog, lub sijhawm tuag yuav tsum tau teeb tsa, thiab cov qauv hauv Circuit Court nyuaj dua.
