18.1 Introduction Uninterruptible power supply (UPS) systems become more and more important due to the growing critical loads, such as telecommunication systems, computer sets, and hospital equipments. In the last few years, an increasing number of publications about UPS systems research have appeared, and, at the same time, different kinds of industrial UPS units have been introduced in the market. Furthermore, the development of novel energy storage systems, power electronic topologies, fast electrical devices, high-performance digital processors, and other technological advances yield new opportunities for UPS systems [King03, Bekiarov02].
