Researches and Applications of A new Variable Coupling-degree Array Integrated Magnetics
摘要
Abstract
The research on magnetic integration inductors have great significance on miniaturization and lightweight of switch converters, and it can also improve the steady-state and dynamic characteristics of the converter. The traditional integral core magnetic integration has some defects such as complexity of design, high costs, and the increase of converter costs and the decrease of efficiency due to high local temperature. Through equivalent segmentation of traditional integral magnetics and analysis of the principle of the equivalent magnetic circuit, a new kind of unit coupling array integrated magnetic topology was put forward. The basic principle of inductor integration was analyzed, the unit position topology and the unit combination topology of array integrated inductors were given, and the relationships between the turn ratio and the reluctance ratio of the self-inductance and the mutual inductance and the coupling degree were analyzed. The consistency of the coupling degree of array integrated inductors with the design criteria was proved by comparison of coupling degree ranges. A simulation model of integrated magnetics was established, and the simulation results show that the steady-state and dynamic characteristics of the 2-phase coupled inductors voltage regulating module (VRM) were better than the traditional coupled inductors. A prototype of coupled inductors was constructed and applied to 2-phase interleaved bi-directional DC-DC converters and 4-phase VRM respectively, and the experimental results were consistent with the simulation results. This proved that the integrated inductors proposed in this paper not only has good practicability but also has good properties compared with the traditional integral magnetic core.关键词
