摘　　要：将TOPSw itch单片精密开关电源中的高频变压器和滤波电感利用解耦磁集成方法集成在一起,推导了磁件等效电路,作了仿真验证。同时设计了集成磁件,并把集成磁件应用到TOPSw itch单片精密开关电源中作了实验验证。经计算,结果表明该集成磁件的可行性。To integrate the high frequency transformer and filter inductance of the TOP Switch singlechip precision switching-mode power supply together with decoupling magnetism integration method, it educes magnetic component equivalent circuit and verifies it with the emulation experiment. At the same time, a test is done in the lab with the special designed integrated magnetic component which is applied into TOPSwitch single chip rigid switching mode power supply. The calculation result shows its feasibility.
