Phapang lipakeng tsa inverter ea mekhahlelo e le 'ngoe le inverter ea mekhahlelo e meraro

1. Inverter ea mohato o le mong

Inverter ea karolo e le 'ngoe e fetola phallo ea DC hore e be sehlahisoa sa karolo e le' ngoe.Phallo ea motlakase / ea hona joale ea inverter ea mohato o le mong ke mohato o le mong feela, 'me maqhubu a eona a lebitso ke 50HZ kapa 60Hz nominal voltage.Motlakase oa lebitso o hlalosoa e le boemo ba motlakase boo tsamaiso ea motlakase e sebetsang ho bona.Ho na le li-voltage tse fapaneng tse fapaneng, ke hore, 120V, 220V, 440V, 690V, 3.3KV, 6.6KV, 11kV, 33kV, 66kV, 132kV, 220kV, 400kV, le 765k ea matla a 1 a poso: , Ke 11kV, 22kV, 66kV, joalo-joalo?

Li-voltage tse tlase tse tlase li ka fihlelleha ka kotloloho ka inverter ka ho sebelisa transformer e kahare kapa seketsoana se nyollang, ha bakeng sa li-voltage tse phahameng ho sebelisoa sesebelisoa sa booster sa kantle.

Li-inverters tsa karolo e le 'ngoe li sebelisoa bakeng sa meroalo e tlase.Ha ho bapisoa le inverter ea mekhahlelo e meraro, tahlehelo ea karolo e le 'ngoe e kholoanyane mme katleho e tlase.Ka hona, li-inverters tsa mekhahlelo e meraro li khethoa bakeng sa meroalo e phahameng.

2. Inverter ea mekhahlelo e meraro

Li-inverters tsa mekhahlelo e meraro li fetolela DC matla a mekhahlelo e meraro.Motlakase oa mekhahlelo e meraro o fana ka hona joale tse tharo tse fapanyetsanang tse nang le li-angles tse arohaneng tsa mekhahlelo.Maqhubu ohle a mararo a hlahisoang qetellong ea tlhahiso a na le amplitude le maqhubu a tšoanang, empa a fapane hanyenyane ka lebaka la mojaro, ha leqhubu le leng le le leng le na le phetoho ea karolo ea 120o pakeng tsa e mong.

Ha e le hantle, inverter e le 'ngoe ea mekhahlelo e meraro ke li-inverter tse 3 tsa mohato o le mong, moo inverter e' ngoe le e 'ngoe e leng likhato tse 120 ho tsoa mohatong,' me mochine o mong le o mong oa karolo e le 'ngoe o hokahane le e 'ngoe ea li-terminals tse tharo tsa mojaro.

Ho na le li-topology tse fapaneng tsa ho aha li-circuits tsa inverter tsa mekhahlelo e meraro.Haeba e le inverter ea borokho, e tsamaisang phetoho ka mokhoa oa 120 degree, ts'ebetso ea inverter ea mekhahlelo e meraro e etsa hore phetoho e 'ngoe le e' ngoe e sebetse ka nako eohle ea T / 6, e hlahisang tlhahiso ea waveform e nang le mehato e 6.Ho na le mohato oa motlakase oa zero lipakeng tsa maemo a motlakase a matle le a mabe a square wave.

Tekanyetso ea matla a inverter e ka eketsoa le ho feta.E le ho haha ​​​​inverter e nang le matla a phahameng a matla, li-inverters tse 2 (li-inverters tsa mekhahlelo e meraro) li kopantsoe ka letoto ho fumana tekanyo e phahameng ea matla.Bakeng sa litekanyetso tse phahameng tsa hona joale, li-inverters tse 2 6-step 3 li ka kopanngoa.
