Sefe e Sebetsang ea Harmonic (AHF)—Mokhahlelo o le Mong
Kakaretso ea Sehlahisoa:
Li-filter tse sebetsang tsa harmonic (AHF) ke karabo e phethahetseng mathateng a boleng ba motlakase a bakoang ke ho sotha ha sebopeho sa maqhubu, matla a tlase, liphetoho tsa motlakase, ho feto-fetoha ha motlakase le ho se leka-lekane ha mojaro bakeng sa mefuta e mengata ea likarolo le lits'ebetso. Ke mofuta oa li-filter tse sebetsang tsa motlakase (APF) tse sebetsang hantle, tse nyane, tse tenyetsehang, tse nang le modular le tse theko e tlaase tse fanang ka karabelo ea hang-hang le e sebetsang mathateng a boleng ba motlakase lits'ebetsong tsa motlakase tse tlase kapa tse phahameng. Li nolofalletsa bophelo ba lisebelisoa nako e telele, ts'epo e phahameng ea ts'ebetso, bokhoni bo ntlafetseng ba sistimi ea motlakase le botsitso, le tahlehelo e fokotsehileng ea matla, ho latela maemo a mangata a boleng ba motlakase le likhoutu tsa grid.
Li-AHF li felisa ho sotha ha sebopeho sa maqhubu ho tsoa meroalong e kang li-harmonics, li-harmonics tse fapaneng le ho notch, le li-voltage tsa harmonic tse bakoang ke maqhubu a harmonic, ka ho kenya hona joale e sothehileng ea boholo bo tšoanang empa e fapane le mohato tsamaisong ea motlakase. Ho phaella moo, li-AHF li ka sebetsana le mathata a mang a 'maloa a boleng ba motlakase ka ho kopanya mesebetsi e fapaneng sesebelisoa se le seng.

Ebe e romela lets'oao la PWM ho boto ea mokhanni ea ka hare ea IGBT ho laola ho bula le ho tima ha IGBT ka maqhubu a 20KHZ. Qetellong e hlahisa hona joale ea puseletso ea mekhahlelo e fapaneng ho induction ea inverter, ka nako e ts'oanang CT e boetse e lemoha hona joale ha tlhahiso e le teng 'me maikutlo a fosahetseng a ea ho DSP. Ebe DSP e tsoela pele ka taolo e latelang ea logic ho fihlela sistimi e nepahetseng le e tsitsitseng haholoanyane.
