摘　　要：分析了一种新型非线性控制方法——脉冲序列控制,通过调整两组预先设定的控制脉冲的组合,实现开关变换器输出电压的调整。脉冲序列控制开关变换器的控制电路简单、可靠,不需要补偿网络。对脉冲序列控制反激变换器的工作原理及控制策略进行了系统、深入地分析,研究了不同负载情况下一个脉冲序列周期内的脉冲组合方式和输出电压纹波,设计了一个脉冲序列控制器。仿真与实验结果验证了理论分析的正确性及控制器设计的可行性。A novel non-linear control method,pulse train（PT）control technique,is introduced and investigated in this paper. The principle of PT control technique is that it regulates output voltage with two preset control pulses. The controller is easy to realize,and no compensation network is needed. The principle and control strategy of PT control are analyzed and studied with flyback converter operating in discontinuous conduction mode（DCM） as an example. The output voltage ripple and the combination of control pulses in a pulse train repetition cycle are analyzed. The pulse train controller is designed. Simulation and experimental results verify the theoretical analysis results and the feasibility of our controller design.
