一種光伏電池- 蓄電池- 超級電容器復合電源系統設計

摘要：常用的蓄電池電源功率特性差且不能從環境中獲取能量補充。本文介紹了一種由光伏電池、蓄電池和超級電容器組成的復合電源系統，提出了開放性、可重組的復合電源動態體系結構，采用相互等效的思想使復合電源控制系統的設計得到了簡化。通過建立復合電源仿真模型，對復合電源在移動機器人上的應用進行了仿真，最后采用設計的移動機器人復合電源系統樣機進行了實驗。仿真結果和實驗結果均說明了本文復合電源設計方法的可行性，也驗證了移動機器人采用復合電源的優越性。 敘詞：復合電源，動態體系結構，移動機器人 Abstract：Common battery power supply often has poor power capability and does not have the function of harvesting energy fromthe environment. This paper introduces a composite power supply system by photovoltaic cell, battery and ultra-capacitor. An open,reconfigurable, dynamic architecture of the composite power supply is proposed, and the designation of the composite power supplycontrol system becomes simplified via employing the idea of mutual equivalent. The simulation model of the composite power supplysystem is established to simulate its application in the mobile robot, and the experiment prototype of the mobile robot using the compositepower supply is designed. The simulation results and the experiment results illustrate the feasibility of the design of the composite powersupply in this article, and also verify the superiority of the composite power supply used in the mobile robot.
