摘　　要：随着全电子引信技术的快速发展和不断成熟,对系统中元器件的小型化提出了新的要求,以便实现更高的集成度。引信系统升压模块中的高压二极管、高压电容等大部分元器件均实现了片式表贴化,而主流的高压变压器仍然采用绕线式,无法同时满足系统要求的输出电压≥2.5kV、体积≤0.6cm^(3)的要求。本研究采用Maxwell软件进行2D电磁仿真和3D建模,基于LTCC技术,选用高性能低温共烧铁氧体(LTCF)材料及配套浆料,将绕组线圈印刷在多层铁氧体生瓷片上,再进行多层堆叠、共烧,实现变压器的扁平化,大幅压缩体积,成功研制出一款小体积片式高压变压器。搭载反激式DC/DC升压电路,变压器实现最高3.03 kV的高压输出,体积减小到0.55 cm^(3)的研制目标。本研究成果同样可推广至发动机高压点火、脉冲功率等领域。With rapid development and continuous maturity of all-electronic fuse technology,new requirements have been put forward for components miniaturization in the system to achieve higher integration.Most of the components such as highvoltage diodes and capacitors in the boost module of the fuse system have been surface mounted,while the mainstream highvoltage transformers still use wire winding,which cannot meet the system's simultaneous requirements on output voltage≥2.5 kV and volume≤0.6 cm^(3).This study used MAXWELL software for 2D electromagnetic simulation and 3D modeling.Based on LTCC technology,materials and matching paste were selected for high-performance low-temperature co-fired ferrite(LTCF).The winding coils were printed on multi-layer ferrite ceramic sheets,and then stacked and co-fired in multiple layers to achieve transformer flattening and significant volume compression.A compact chip-type high-voltage transformer was successfully developed.Equipped with a flyback DC/DC boost circuit,the transformer could achieve a high output voltage of up to 3.03 kV,and the volume is reduced to the development goal of 0.55 cm^(3).The findings could also be extended to fields such as high-pressure ignition in engines and pulse power.
