vi PREFACE Power Electronics is leading a revolution in the field of electrical energy conditioning for industrial applications. Near to the year 2010 more than fifty percent of the total electrical energy, which is consumed in the developed countries, is estimate to be processed before the final use into the loads. Such a trend is mainly based on the innovations on industrial products, and on the achievements in the field of power converters, electronics and control techniques. Generally speaking, Power concerns the generation, transmission and distribution of electric power to the final users. On the basis of these processes, Electronics can boast a growing importance due to the widespread application of solid-state devices and signal processing circuits for energy conversion. On the other side, Control represents an indispensable field of Power Electronics whereas excellent stability and dynamic performances are strict requirements of actual industrial applications. Due to the interaction among the aforementioned disciplines, the design of a highly efficient conversion system for power applications needs multidisciplinary expertize in the sectors of power devices, power converters, signal processing and control. Although this poses new challenges to power application designers, the role of Power Electronics, anyway, has been fundamental in increasing, in the course of the years, the conversion efficiency, in reducing the mass and cost of power conditioning systems, in enhancing the dynamic performances, and in providing new equipment with these capabilities to the large demand coming out from the high technology products. By this way, has been created the basis for the development of several applications which cover a wide power range from few watts to several hundreds of megawatts. The success in the fields of computers and communication equipment is linked to the advances achieved in Switch-Mode Power Supply (SMPS) systems and Uninterruptible Power Supply (UPS) systems, which provide, respectively, regulated dc power supplies and uninterruptible power supplies. The primary task in such applications is the attainment of a high-efficiency power conversion which is required for an optimal delivering of the energy to the users. Centralized power supply systems feature strong limitation in terms of power losses, due to the low distribution voltage of 48 V, which advises against their use in modern Telecom applications. To overcome
