针对微处理器对Buck变换器快速动态响应速度的特殊要求,提出了Buck变换器电路理想的过渡过程波形。通过对理想波形的定量分析,得到了其实现方法:电容电流平方滞环(CCSH)控制方法。Matlab仿真结果验证了其优越的控制性能。
According to the requirement of fast transient response of microprocessor, an ideal Buck converter circuit variables variations waveform has been proposed. Based on the quantitative analysis of the ideal waveform, a new control technique, called capacitor current square hysteresis (CCSH)control technique,is derived. Matlab simulation results show the advantage of the new control technique.
