摘　　要：为提高推挽变换器的电流稳定性和系统可靠性,在推挽变换器的小信号数学模型基础上,建立推挽变换器的全状态变量双环控制系统,同时给出了控制系统的具体设计过程,并通过仿真软件对具体设计过程进行分析;仿真对比和实验结果表明:双环控制器提高了推挽电路的输出电压和系统电流稳态和动态性能,提高了系统可靠性,同时也验证了控制策略的正确性。In order to enhance the push-pull converter＇s current stability and the system reliability, the full- state variable dual-loop control system with the full- state variable is constructed based on the push-pull converter＇s small signal mathematical model. The circuit control system＇s design process is given in the paper simultaneously , and the concrete design process is analyzed through the simulation software. The simulation comparison and experimental resultsindicated： the dual-loop controller enhanced push-pull circuit＇s output voltage and the system current stability and the dynamic property, at the same time the control system design is proved correctly.
