This study proposes an LLC series resonant converter with a current doubler using a coupled inductor as a
rectification circuit for the secondary side. The current doubler circuit is generally used for a high-voltage input
and low-voltage output circuit to obtain high efficiency with small transformer turn ratio. However, an
inductive circuit is not generally used in the secondary side of an LLC series resonant converter. If inductive
components exist on the secondary side, the resonant characteristics are changed through the secondary
inductive circuit. Mathematical analysis shows that the secondary-side current doubler with coupled inductor is
not affected by the resonant characteristic of the primary LLC if leakage inductance occurs in the coupled
inductor. Results of the analysis are proven by simulation; an experiment is also conducted for the proposed
circuit.
