Two quadrants Battery Simulator, A New Approach

摘要

Battery simulator is a two quadrants DC regulated power supply unit. It is designed to simulate the V/I characteristics of chemical batteries used to store electrical energy from photovoltaic power generation system. The photovoltaic power generation system could be for terrestrial use or for space use, such as in spacecrafts. To evaluate power systems and associated logics of this kind, battery simulators are extensively used. These units should have capability of sinking and sourcing to simulate charge and discharge characteristics of battery at programmable voltage levels. Various methods of realizing such simulators are discussed in this paper and a novel concept of realizing two quadrants Battery Simulator with the off-the shelf DC Power source is brought out with experimental results.
