Parizvino, kune mhando dzakawanda dzemaDC/DC converters ari pamusika, resonant converter imhando yeDC/DC converter topology, nekudzora switching frequency kuti uwane constant output voltage resonance circuit. MaResonant converters anowanzo shandiswa muma high voltage applications kuti anyatsoita waveforms, awedzere simba, uye aderedze kurasikirwa kwe switching kunokonzerwa nema high frequency power switches akadai seMOSFETs neIGBTs. Zvakakosha kuziva kuti LLC circuit inowanzo shandiswa muma resonant converters nekuti inogonesa zero voltage switching (ZVS) uye zero current switching (ZCS) mu operating range, inotsigira high switching frequency, inoderedza footprint yezvikamu, uye inoderedza electromagnetic interference (EMI).
Dhirowamu yechirongwa chekushandura resonant
Chinoshandura resonant chakavakirwa pa resonant inverter inoshandisa network yemaswitch kushandura DC input voltage kuita square wave, iyo inozoshandiswa ku resonant circuit. Sezvakaratidzwa muMufananidzo 2, resonant circuit ine resonant capacitor Cr, resonant inductor Lr uye magnetizing inductor Lm ye transformer in series. Dunhu re LLC rinosefa chero harmonics yepamusoro-soro nekusarudza simba guru pa square wave resonant frequency uye kuburitsa sinusoidal voltage kuburikidza ne magnetic resonance. Iyi AC waveform inowedzerwa kana kuderedzwa ne transformer, inogadziriswa, uye yozosefa kuti igadzire converted DC output voltage.
Chinoshandura cheDC/DC chakareruka cheLLC chinoshandura resonant DC/DC
Mwero wepakati pechikwere (RMS) we capacitor ndeimwe yematanho akakosha ekutarisisa pakusarudza capacitor ye resonant Cr yakakodzera yeDC/DC converter. Inokanganisa kuvimbika kwe capacitor, voltage ripple, uye mashandiro ese e converter (zvichienderana ne topology ye resonant circuit). Kupisa kunokanganiswawo neRMS current nezvimwe zvinorasikirwa mukati.
