Kusanthula kwa Parallel Resonant Inverter kwa Kupereka Mphamvu kwapakatikati

Parallel resonant inverter, katundu wake ndi ofanana resonant katundu. Kawirikawiri gwero lamakono likufunika kuti lipereke mphamvu. Pakuwotha kwa induction, gwero lapano nthawi zambiri limapangidwa ndi chowongolera komanso chowongolera chachikulu. Chifukwa cha mtengo waukulu wa inductance, zitha kuyerekezedwa kuti zomwe zili kumapeto kwa inverter zimakhazikika. Mwanjira ina kuyatsa ndi kuzimitsa zida zowongolera pa inverter kumatha kupeza mawonekedwe osinthika a square wave pakupanga kwa inverter. The matalikidwe a panopa zimadalira mtengo panopa athandizira athandizira inverter, ndipo pafupipafupi zimadalira chipangizo. pafupipafupi ntchito. Monga momwe tawonetsera pa Chithunzi 2.4, inverter yomwe imagwirizanitsa capacitor yamalipiro ndi coil katundu (L ndi R) mofanana ndi katundu wa mlatho wa inverter amatchedwa inverter yofanana ndi resonant. A inductance Ld yayikulu imalumikizidwa motsatizana ndi magetsi a DC mu inverter yofananira, kotero katundu wapano ndi wokhazikika ndipo samakhudzidwa ndi kusintha kwa katundu. Pamene mphamvu yolemetsa si 1, gawo lamagetsi lamagetsi la katundu lidzawonjezedwa ku chipangizo chosinthira. Pofuna kuteteza IGBT kuti isawonongeke ndi magetsi obwerera kumbuyo, diode yofulumira iyenera kulumikizidwa mndandanda ndi IGBT. Ngakhale gawo la IGBT litagwiritsidwa ntchito, chifukwa mkati mwake muli anti-parallel diode yofulumira, IGBT siyingapirire voliyumu yakumbuyo, ndipo ma diode othamanga kwambiri sangathe kuthetsedwa, apo ayi chipangizocho chidzawonongeka chifukwa cha kufalikira komwe kumachitika chifukwa cha mphamvu yake. reverse voltage. Malinga ndi mgwirizano wamagetsi ndi gawo lapano la dera la tank tank, inverter yofananira imatha kugwira ntchito m’malo atatu: resonance, inductive and capacitive states. Chifukwa cha kukhalapo kwa inductance yaikulu Ld, kuti apitirizebe kupitirizabe, panthawi ya kusintha, milatho yapamwamba ndi yapansi Mlatho wa IGBT uyenera kutsata mfundo yoyamba kuyatsa ndikuzimitsa, ndiko kuti, payenera kukhala nthawi yowonjezera RT. Kutalika kwa nthawi yophatikizika kumagwirizana kwambiri ndi inverter output wiring inductance. Kuchuluka kwa inductance, kumatenga nthawi yayitali..
