指数平滑法是对时间序列进行预测常用的方法之一,其理论基础是趋势外延，即未来一定时期内事物在数量上的演变特征不脱离过去的发展趋势,预测值是以前所有观测值的加权和,且对不同的数据给予不同的权数,越近期数据给予越大的权数,越远期的数据给予越小的权数。(Exponential smoothing method is commonly used to predict the time series one of the ways, the theoretical basis of the trend of the extension, that is, a certain period of time what the next evolution in the number of characteristics are not out of the development trend of the past to predict the value of all previous observations is the weighted and, on different data and different weights given to more recent data to give greater weights, the more long-term data to give the smaller weights.)

分布式电源系统具有大容量、高效率、高可靠性等优点，其广泛采用多模块并联方式，但模块间因为控制参数不同，且各模块输出是电压源性质，如果没有特殊的均流措施，输出电压的微小偏差会导致输出电流很大的差别，一旦某个模块过载，将造成一个或多个功率器件热应力过大，从而降低系统的稳定性。(The
current-sharing is one of the key technologies in Paralleled DC/DC converters to distribute the load current equally.
Common current-sharing technologies are divided into passive and active methods. With different kinds of output
voltage regulation and different means of current sharing line production, several control methods are proposed in the
active methods. The principle of current sharing technologies and main current-sharing methods are systematically
analyzed, some new current-sharing methods which include masterless modular current-sharing (MMCS) technique
and no current share line control are summarized. The technology of current sharing tends toward the direction of
digitalization and intellectualization with digital control.
