摘要 提出了一种基于电容电荷平衡的滞环控制策略,通过Buck变换器为例介绍了其工作原理。首先,利用状态空间平均法搭建其小信号模型,在此基础上,讨论了控制器参数对整个系统的影响,并和传统电压控制Buck变换器进行了频域仿真和结果对比分析,最后通过实验进行了验证。仿真和实验结果表明,提出的滞环控制策略比传统电压控制Buck变换器具有更快的瞬态响应速度和更好的抗干扰能力。

关键词 Buck变换器滞环控制小信号模型瞬态响应    
Abstract:This paper proposed a hysteresis control strategy based on capacitor charge balance, the operation theory is described with a Buck converter as an example. Firstly, the small signal model is derived by the state-space averaging method. Based on this, the influence of controller parameters on system is discussed, and frequency-domain simulation is performed and analysed by contrast on traditional voltage controlled and propoede hysteresis controlled Buck converter, finally, the experimental result are given. The simulation and experimental results have shown that the proposed control strategy has faster transient response and better anti-interference ability than traditional voltage controlled for Buck converter.
Key wordsBuck converter    hysteresis control    small signal model    transient response
