| 摘 要： | 针对开关DC-DC变换器的非线性控制问题,提出多级脉冲序列控制方法,并对工作于电感电流断续模式的多级脉冲序列控制Boost变换器进行分析。多级脉冲序列控制策略通过在若干连续开关周期内,产生能量等级不同的控制脉冲信号所组成的脉冲序列,实现对DC-DC变换器功率电路的控制。分析了多级脉冲序列控制的基本原理和工作过程,并对多级脉冲序列控制断续工作模式Boost变换器进行了稳态工作特性分析和稳定性分析。与已有的脉冲序列控制相比,采用多级脉冲序列控制的Boost变换器在具有快速动态响应能力的同时,能够有效减小稳态工作时的输出电压纹波。仿真和实验结果验证了控制策略的可行性以及理论分析的正确性。

| Abstract: | For the nonlinear control problem of switching DC-DC converters,a new control technique called as multilevel pulse train(MPT) was proposed.MPT controlled Boost converter operating in discontinuous conduction mode(DCM) was studied in this paper.By using MPT control method,multilevel control pulses were combined to generate a pulse train for the control of power converters.The principle and process of MPT control technique were introduced.Then the steady-state and stability analysis of MPT controlled DCM Boos... |
