Ka tsoelo-pele ea theknoloji ea morao-rao, ho hlaha ha li-inverters ho fane ka boiketlo bo bongata bakeng sa bophelo ba motho e mong le e mong, joale inverter ke eng?Inverter e sebetsa joang?Metsoalle e nang le thahasello ho sena, tloho 'me u fumane hammoho.
Inverter ke eng:
Inverter e fetola matla a DC (betri, betri ea polokelo) ho matla a AC (ka kakaretso 220V, 50Hz sine wave).E na le borokho ba inverter, logic ea taolo le potoloho ea filthara.E sebelisoa haholo ho li-air conditioner, liholo tsa lehae, mabili a silang a motlakase, lisebelisoa tsa motlakase, mechine ea ho roka, DVD, VCD, lik'homphieutha, lithelevishene, mechine e hlatsoang, li-hoods, lihatsetsi, VCRs, massagers, fans, mabone joalo-joalo Linaheng tse ling, ka lebaka la ho isa tekanyong e phahameng ea ho kenella ha likoloi, inverter e ka sebelisoa ho hokahanya betri ho khanna lisebelisoa tsa motlakase le lisebelisoa tse fapaneng ho sebetsa ha u tsoa mosebetsing kapa maetong.
Molao-motheo oa ts'ebetso ea inverter:
Inverter ke DC ho AC transformer, eo ha e le hantle e leng mokhoa oa ho fetola motlakase le converter.Mofetoleli o fetola motlakase oa AC oa marang-rang a matla hore e be sehlahisoa se tsitsitseng sa 12V DC, ha inverter e fetola motlakase oa 12V DC ka Adapter hore e be AC e phahameng-frequency high-voltage;likarolo ka bobeli li boetse li sebelisa mokhoa o sebelisoang khafetsa oa pulse wide modulation (PWM).Karolo ea eona ea mantlha ke taolo e kopaneng ea PWM, Adapter e sebelisa UC3842, 'me inverter e sebelisa chip ea TL5001.Mofuta oa motlakase o sebetsang oa TL5001 ke 3.6 ~ 40V.E na le amplifier ea liphoso, regulator, oscillator, jenereithara ea PWM e nang le taolo ea libaka tse shoeleng, potoloho e tlase ea ts'ireletso ea motlakase le potoloho e khuts'oane ea tšireletso.
Karolo ea ho kenya:Ho na le matšoao a 3 karolong ea ho kenya, 12V DC e kenyang VIN, mosebetsi o nolofalletsa voltage ENB le Panel pontšo ea hona joale ea taolo DIM.VIN e fanoa ke Adapter, ENB voltage e fanoa ke MCU ka lebokose la li-motherboard, boleng ba eona ke 0 kapa 3V, ha ENB = 0, inverter e sa sebetse, 'me ha ENB = 3V, inverter e le boemong bo tloaelehileng ba ho sebetsa;athe DIM voltage E fanoe ke boto e kholo, mefuta e fapaneng ea eona e pakeng tsa 0 le 5V.Litekanyetso tse fapaneng tsa DIM li khutlisetsoa ho terminal ea maikutlo ea molaoli oa PWM, 'me hajoale e fanoeng ke inverter ho mojaro le eona e tla fapana.Ha boleng ba DIM bo nyane, bo nyane ba tlhahiso ea hona joale ea inverter.kholoanyane.
Potoloho ea ho qala motlakase:Ha ENB e le maemong a holimo, e ntša motlakase o phahameng ho khantša tšupu ea mabone a morao a Panel.
Selaoli sa PWM:E na le mesebetsi e latelang: motlakase oa ka hare oa referense, amplifier ea liphoso, oscillator le PWM, tšireletso ea overvoltage, tšireletso ea undervoltage, tšireletso ea potoloho e khutšoanyane, le transistor e hlahisoang.
Phetoho ea DC:Potoloho ea phetoho ea motlakase e entsoe ka MOS switching tube le inductor ea polokelo ea matla.Pulse ea ho kenya e matlafatsoa ke push-pull amplifier ebe e khanna MOS tube ho etsa ketso ea ho fetola, e le hore motlakase oa DC o lefelle le ho ntša inductor, e le hore karolo e 'ngoe ea inductor e ka fumana motlakase oa AC.
LC oscillation le potoloho ea tlhahiso:etsa bonnete ba hore motlakase oa 1600V o hlokahalang hore lebone le qale, le ho fokotsa motlakase ho 800V ka mor'a hore lebone le qale.
Maikutlo a ho tsoa ha motlakase:Ha mojaro o ntse o sebetsa, motlakase oa sampole o khutlisetsoa morao ho tsitsisa tlhahiso ea motlakase ea inverter.
