高压引信电路仿真与模块一体化设计OA

To meet the demands for miniaturization,integration,and performance improvement of fuze boost ignition circuits,this study proposed a design method for a fuze module with fast boosting,miniaturization,and high integration based on Low Temperature Co-fired Ceramic(LTCC)technology.Firstly,considering the parasitic parameters of components,by modeling and deriving the flyback boost circuit,we proposed a complete set of boost circuit parameter design methods.Secondly,the flyback boost unit(including high and low voltage sides),capacitor discharge unit,and voltage divider sampling unit were systematically integrated using LTCC technology.Surface mount devices were adopted and the layout was optimized to reduce the area of the discharge loop and enhance the discharge performance.Simulation results show that the peak voltage at the drain of the MOSFET is effectively clamped to 240.2 V(originally 527.3 V);the boost time is shortened to 30 ms(with the boost voltage reaching 1390 V),which represents a 68.9%improvement compared with existing studies.The overall module size measures only 50 mm×22 mm×9.6 mm,enabling system control of the boost and discharge functions while providing real-time monitoring of the boost voltage.
