坦克火控系统三相交流软开关静变电源设计

Design of Soft-switched Three-phase AC Static Inverter of Tank Fire Control System

采用高频电力变换技术,对装甲车辆火控系统中的36V/400 H z三相交流供电方式进行了替代研究。试验结果表明,在三相交流软开关静变电源的设计中,引入高频脉冲直流环节可以有效地降低开关器件损耗,减小交流供电装置的体积与噪声,提高电能转换效率。

Adopt the high-frequency power transform technology; take a substitute research on 36V/ 400Hz three-phase AC current supply mode of the fire control system in the armored vehicles. The experimental results show that, introducing the high-frequency pulse D.C. link can decrease the switching dissipation of the equipment effectively, reduce the volume and noise of the converter, improve the conversion efficiency of electric energy during the design of soft-switching three-phase static inverter.
