Kuongororwa kweParallel Resonant Inverter ye Yepakati Frequency Power Supply

Parallel resonant inverter, mutoro wayo wakafanana resonant mutoro. Kazhinji chitubu chemazuva ano chinodiwa kupa simba. Mukupisa kwe induction, iko kwazvino sosi inowanzo umbwa neinogadzirisa uye inductor yakakura. Nekuda kweiyo yakakura inductance kukosha, inogona kufananidzwa kuti ikozvino pamagumo ekuisa inverter yakagadziriswa. Alternately kubatidza uye kudzima zvigadziriso zvinodzoreka pane inverter zvinogona kuwana alternating square wave ikozvino pakubuda kweiyo inverter. Iyo amplitude yezvino inotsamira pane ikozvino kukosha kwekupinza kweiyo inverter, uye kuwanda kunoenderana nechigadzirwa. kushanda frequency. Sezvinoratidzwa mumufananidzo 2.4, iyo inverter inobatanidza capacitor yekubhadhara uye coil coil (L uye R) inofananidzwa semutoro webhiriji inverter inonzi parallel resonant inverter. Iyo hombe inductance Ld yakabatana munhevedzano neiyo DC magetsi emagetsi mune parallel inverter, saka mutoro wazvino uno unogara uye haukanganisike nekuchinja kwekuremerwa kwemutoro. Kana iyo simba remutoro isiri 1, iyo reactive voltage chikamu chemutoro ichawedzerwa kune inoshandura mudziyo. Kuti udzivise IGBT kubva pakukuvadzwa nereverse voltage, diode inokurumidza inofanira kunge yakabatana munhevedzano neIGBT. Kunyangwe kana IGBT module ikashandiswa, nekuti mukati mune anti-parallel inokurumidza diode mukati, iyo IGBT haingamirire reverse voltage, uye iyo yakateedzana inokurumidza diode haigone kudzimwa, zvikasadaro mudziyo uchakuvadzwa nekutenderera ikozvino kunokonzerwa neiyo. reverse voltage. Zvinoenderana neiyo voltage uye yazvino nhanho hukama hweinoremedza tangi redunhu, iyo parallel inverter inogona kushanda mumatunhu matatu anoshanda: resonance, inductive uye capacitive nyika. Nekuda kwekuvapo kwehombe inductance Ld, kuitira kuchengetedza ikozvino kuenderera mberi, panguva yekufamba, mabhiriji ekumusoro uye ezasi Ruoko IGBT inofanirwa kutevedzera mutemo wekutanga kuvhura uye wozodzima, ndiko kuti, panofanira kunge paine kupindirana nguva RT. Kureba kweiyo commutation inopindirana nguva inowirirana zvakanyanya neiyo inverter inobuda wiring inductance. Iyo yakakura inductance, iyo yakareba nguva..
