摘要
深入研究了工作于电感电流断续导电模式(discontinuous conduction mode,DCM)的脉冲序列控制Boost变换器,在分析每个开关周期内高、低功率脉冲控制下输出电压变化量的基础上,研究了不同负载下脉冲序列控制DCM Boost变换器在一个功率脉冲循环周期内高、低功率控制脉冲组合方式和输出电压纹波,为脉冲序列控制方案的设计提供了必要的依据。基于PSIM电路仿真,得到了不同负载时的时域波形,仿真结果验证了控制脉冲组合方式、纹波分析结果的正确性及控制方案的可行性。本文的分析方法和研究结论对脉冲序列控制开关变换器的设计和运行具有重要的指导意义。
This paper explores pulse train controlled boost converter operating in discontinuous conduction mode （DCM）. By analyzing the output voltage variations under the high and low power pulse controls in each switching cycle, the paper also investigates the high and low power control pulse combinations and output voltage ripples in a power pulse train repetition cycle of pulse train controlled DCM boost converter with different loads are investigated, which provide the necessary basis for the design of pulse train control scheme. By using PSIM circuit simulations, the time-domain waveforms under different loads are obtained. Simulation results verify the correctness of the control pulse combinations and ripple analysis results and the feasibility of the proposed control scheme. The analysis methods and research results in this paper possess important guiding significance in the design and operation of pulse train controlled switching converters.
