  • Patent number: 11855529
    Abstract: The invention discloses a novel control scheme/strategy for the stacked structure LLC resonant converter. The control scheme includes a control signal as a gating signal of the fourth switch, and gating signals of the first, second and third switches that are operably generated according to the gating signal of the fourth switch. The gating signals of the second switch has a same duty ratio as and a phase shift of 180 degrees from the gating signal of the fourth switch. The gate signals of the first and third switches are complementary with the gate signals of the second and fourth switches, respectively. By adopting the control strategy, a three level LLC resonant network input voltage is generated, which includes Vin, Vin/2 and 0.
