More Information
Summary:A current resonant type DC voltage converter includes: a switching circuit (10) configured to generate an AC voltage from a DC input voltage (Vin); a LC resonance circuit (20) configured to resonate in response to application of the AC voltage to a resonant capacitor (21) and a resonant coil (22); a transformer (30) having a primary side connected in series to the LC resonance circuit; a parallel resonant inductance (Lm1) present in parallel to the transformer; a rectifier circuit (40) configured to rectify a current appearing on a secondary side of the transformer (30) to generate a DC output voltage (Vout); and a parallel resonant inductance adjustment circuit (50) configured to change the parallel resonant inductance (Lm1).
