Abstract

In this paper, expandable bobbin type multiple integrated coupled-inductor applied 4-paralled switching rectifier was proposed. To design the proposed inductor easily, inductance designing formula was derived through magnetic circuit analysis of the 4-paralleled integrated coupled-inductor. Furthermore, to verify practicality of the proposed inductor, it was applied in 600W class 4-paralleled interleaved switching rectifier, and the steady-state characteristics of the proposed inductor and discrete inductors were compared. Consequently, it was showed that the proposed inductor can replace the conventional discrete inductors with alternative electrical characteristic standard, hence miniaturization of the SMPS can be achieved. From the test result, test circuit with the proposed inductor showed maximum 97.1% of power conversion efficiency and under 18W of power loss where the circuit with discrete inductors showed 96.7% and 20W respectively.
