Dual transformer device for power converters

摘要: A dual transformer device (34) for use in a power converter (30) is provided. The preferably implemented as an integrated magnetics suitable high density converters. Two transformers, T1 and T2, have series connected primary windings (300 302), secondary (304 306) at common node (312). T2 magnetizing inductances, L1 L2, that independently store energy responsive to AC voltage, V p . Diodes, D1 D2, operate rectify substantially out-of-phase voltages, S1 S2 produce rectified voltage R D2 cause L2 discharge such the magnitude of output current, I5, always equal sum currents, I An filter (38) reduces current ripple I5 Another inductance, L3, supplies supply (32) reduce switching losses.
