The Research On The Array Planar Integrated Magnetics Of The Switch Transformer

In search of light ,small, thin of the switch power ,this paper summarizes the technique of integrated magnetic ,introducing the normal research method of integrated magnetics .With the research on many integrated magnetics ,in the base of the theory of the decoupled integrated ,dimensioning the core of the traditional integrated magnetics ,it introduces a new integrated magnetics-"array-planar integrated magnetics(APIM)".Then it starts from the view of combining the magnetic circuit and circuit, analyzing the integration of the array planar inductor and inductor (APIT-L+L), and the theory of integrated magnetic on the array planar inductor and transformer (APIM-L+T), it introduces many integrated project of APIM-L+L and APIM-L+T, building the equivalent circuit and verifying the feasibility of the APIM by the simulation and experiment research . This paper also analyses the influence of the winding structure and distribution on the planar transformer and planar inductor with the magnetic field simulation soft Maxwell , and provides the reference gist for the design of APIM. In the base of those , this paper introduces the implement method of the planar APIM, designing the APIM in the base of cuk with the isolate transformer ,integrating the two inductors and isolate transformer of the cuk with the isolate transformer ,and use Saber soft for the simulation and experiment .The result verifies the APIM have the good performance as the discrete magnetics .
