Ch4. LLC Resonant Converter - Virginia Tech
vtechworks.lib.vt.educonverter, the resonant tank is still in series. It is called parallel resonant converter because in this case the load is in parallel with the resonant capacitor. More accurately, this converter should be called series resonant converter with parallel load. Since transformer primary side is a capacitor, an inductor is added on the secondary ...
