介绍了太阳能电池等可变电源达到最大功率点的动态过程。该过程在瞬态期间几乎一个周期一个周期地跟踪最大功率。利用来自自然开关纹波的信息而不是外部扰动来支持最大化过程。该方法对于DC-DC功率变换器是全局稳定的，只要存在开关动作。使用这种方法进行控制的升压功率转换器的原型可以在几毫秒的时间尺度上跟踪功率瞬变。这种性能可以通过一个简单的模拟控制结构来实现，它支持以最小的损耗进行功率处理。
A dynamic process for reaching the maximum power point of a variable power source such as a solar cell is introduced. The process tracks maximum power nearly cycle-by-cycle during transients. Information from the natural switching ripple instead of external perturbation is used to support the maximizing process. The method is globally stable for DC-DC power converters, provided that a switching action is present. A prototype boost power converter that uses this method for control can follow power transients on time scales of a few milliseconds. This performance can be achieved with a simple analog control structure, which supports power processing with minimum loss.
