SLLC Resonant Converter for Bidirectional Power Conversion using auxiliary inductor

Auxiliary inductor application exposes the SLLC resonant converter for two-way power cane. SLLC resonant converter of the present invention comprises a first and a first winding end, the first and the first coil end parallel connected to the primary side first and second auxiliary inductors for each of the second transformer of the second transformer having a parallel structure the primary side end to; And a forward motion during has a second winding end, wherein the first and single second winding of the second transformer of the first and the second transformer comprises a serial connection circuit when gajina a circuit configuration that is connected in parallel operation reverse motion operation respectively first and second resonant capacitors and the first and second resonance capacitor and the other terminal of the first and second secondary winding only the outlet side each parallel connected to the other end of the first and the second comprising a secondary inductor of the transformer is connected to the the second comprises a side end, during forward operation, the first and second claim wherein the first coil end and the primary side of the transformer a first and a second winding of the first and second transformer by the current change of the storage inductor stage and the first and first when the second resonant capacitor and the secondary-side first and second current change induced in each of the auxiliary inductors and to charge the secondary-side voltage so as to have the LLC resonance characteristics, and the reverse operation and the a second transformer A first winding the primary current changes induced in the first and second secondary inductors, each of said first and second first winding end and a leakage inductance and the first and second transformer second winding ends of the transformer stage and claim to have a resonant capacitor and the LLC resonant characteristics associated with the second winding end and is characterized in that to fill the primary side voltage.
