摘　　要：基于推挽拓扑结构设计,研究了一种全电坦克炮控系统用升压电源,但推挽电路存在着难以消除的偏磁现象,使得升压电源的可靠性降低。详细阐述了推挽电路中偏磁现象产生的原因,针对性地提出了串入箝位电容、采用电流内环控制、优化电路布局等偏磁抑制方法。实验结果表明：所采用的推挽电路偏磁抑制方法具有结构简单、抑制效果好的优点,提高了全电坦克炮控系统升压电源的可靠性。Based on the design of push-pull topology structure, the boost power supply of electrical tank gun control system is developed. However, the push-pull circuit has the phenomemon of intractable magnetic biasing, which makes the reliability of boost power supply reduced. The reasons of causing bias are demonstrated and bias restraining methods such as adopting serial clamp capacitors, inner loop current control and optimizing circuit layout are presented in this paper. The experimental results show that those restraining methods of push-pull circuit have the merits of simple configuration and good effect of bias restraining so that the reliability of the boost power supply of the electrical tank gun control system can be improved.
