摘　　要：分析了在正弦脉宽调制波的作用下推挽式电压型逆变器的各种工作模态,并在此基础上阐述了推挽变压器线圈间的能量流向与诸漏感的作用时间和涉及空间的关系,以及提出了该逆变器的一种数学模型,并基于该模型用Matlab进行仿真。该模型概念清晰重点突出,仿真方法便于再现,仿真结果和实验验证了数学分析的正确性,有利于把握变压器外特性、改善开关环境和推挽类功率变换器的控制设计。Analysed various working modes of push-pull voltage source inverter under the action of SPWM. On the basis, the relationship among the direction of energy flow within windings, the action time and associated coil was described, and a mathmatical model of the push-pull transformer was proposed, Matlab simulation results were also provided based on this model. The model is clear in concept focused and the simulation method is easy to reproduction, the results of the simulation and experiment verify the correctness of mathematical analysis, this would be propitious to grasp external characteristics of transformer, improve the switching environment and the control design of push-pull type power converter.
