在当今具有环保意识的社会中，储能技术变得越来越重要。在传统的恒定电源电压下对电容器直接充电的方法中，能量的耗散量与电容器中存储的能量相同。本文提出了通过连续改变DC-DC下变频器的占空比对电容器进行分段充电的方法。在N步充电中，与传统的直接充电相比，能量消耗降低到N的1/N。通过SPICE仿真和电路板实验验证了能量的降低，通过四次充电和八次充电的电源电流分别证实了能量的降低。
Energy storage technology is becoming more and more important in today's environmentally conscious society. In the conventional method of directly charging a capacitor under a constant power supply voltage, the amount of energy dissipation is the same as the energy stored in the capacitor. In this paper, we propose the stepwise charging of a capacitor by consecutively changing the duty ratio of the DC-DC down converter. In N step charging, the energy dissipation is reduced to one Nth when compared with the conventional direct charging. The reduction of the dissipated energy is verified by SPICE simulations and by breadboard experiments, through which an energy reduction of one fourth and one eighth is confirmed from the measured power supply currents in four and eight step charging, respectively.
