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.
