Abstract :
This paper proposes a novel modulation method of the full bridge three-level LLC resonant converter. The voltage gain of the converter is analyzed by First Harmonic Approximation technique using this modulation method. Therefore designers can easily calculate the converter parameters. A 385V input, 225 to 378V/6.6kW output prototype converter shows 98.14% peak efficiency.
