Abstract:In order to meet the power needs of a new generation of low-voltage,high-current,and fast transient response converter,a “UUUU” shape coupled inductor structure is proposed.The flux distribution of the coupled inductor is firstly analyzed in order to establish the magnetic circuit model,and thus derive the formula for inductance,leakage inductance,and mutual inductance.Then the design method of coupled inductor is provided.Through simulation and experiments,the correctness of the magnetic component model is validated.The proposed “UUUU” shape coupled inductor has the characteristics of simple processing,large inductance,more uniform magnetic flux density distribution,and good DC superposition property.The “UUUU” shape coupled inductor can be applied to the interleaving bidirectional DC-DC converter with small phase current ripple and high efficiency.
