摘要:
 摘要:为了提高Boost变换器的暂态性能,减小非最小相位反应引起的负调对系统的影响,利用脉冲波形积分法建立了Boost变换器工作在电感电流连续模式下的小信号数学模型,获得了系统输入-输出以及控制--输出的传递函数,为Boost变换器暂态性能优化提供了理论依据。利用该模型分析了电感、电容、负载、占空比、频率等参数对系统暂态性能和系统非最小相位引起的负调电压的影响。研究结果表明:较大的电感、最重负载、较大的占空比使得系统的零点更靠近原点,系统的非最小相位反应即负调现象更加明显;不同的电容值会影响系统的暂态性能和输出电压纹波,对负调反应没有影响。给出了提高系统暂态性能和减小非最小相位反应的参数选择思路,为Boost变换器优化设计提供了理论依据。仿真和实验结果验证了参数选择设计的合理性。
Abstract:
 Abstract:In order to improve the Boost converter’s transient performance and reduce the negative overshoot effect because of non-minimum-phase reaction on system,the small signal mathematics model of Boost converter worked in inductor current continuous mode was established with pulse waveform integral method. The transfer functions from input to output and from control to output were obtained. The theoretical basis for the Boost converter transient performance optimization was provided. The effect of transient performances and negative over-shoot on there parameters such as inductance,capacitance,load,duty ratio and frequency were analyzed with the mathematics model. Research results show that the larger the inductance,the heavy load,large duty can make the system zero near the origin,and the over-shoot phenomenon is more obvious because of non-minimum-phase reaction on system. Different capacitance values have an impact on transient performance and output voltage ripple and have no effect on the overshoot phenomenon. The principle of parameter selection for improving system transient performance and reducing non-minimum-phase reaction were given. The theoretical basis for optimal design of Boost converter was provided. The simulation and experimental results verify the rationality of the parameter selectron.
