    Abstract— The utilization of fuel cells for distributed power genera- tion requires the development of an inexpensive inverter that converts a fuel cell’s variable dc output into useful ac. To encourage this develop- ment the US Department of Energy and the IEEE setup and sponsored a national US student competition with a substantial first prize going to the lowest cost working fuel cell inverter: the 2001 Future Energy Chal- lenge (FEC). This paper describes the work of the University of Wis- consin FEC Team. It discusses the topology used to achieve the said ob- jective, the rationale used in choosing this topology, detailed component selection optimized to minimize cost, and the dc/dc and dc/ac converter control. Finally some conclusions are made and a new total-system- approach design using a high voltage fuel cell is proposed to further reduce the cost of the inverter.

    found in the literature. These problems have become one of the major concern, especially, with the use of power electronics devices which are sensitive to the variation of power supply. Among these problems Voltage Sag & Swell are identified as major concern to the electrical consumers. Voltage Sag is one of the most occurring power quality problems that cause severe problems and losses to industry. With the power systems restructuring and shifting trend towards distributed and dispersed generation, the concern of power quality has taken newer dimensions. In developing countries like India, where the variation of power frequency and many such other problems related to power quality are themselves a serious question, it is very vital to take…

    The APF technology is now mature for providing compensation for harmonics, reactive power, and/or neutral current in ac networks. It has evolved in the past quarter century of development with varying configurations, control strategies, and solid-state devices. APF’s are also used to eliminate voltage harmonics, to regulate terminal voltage, to suppress voltage flicker, and to improve voltage balance in three-phase…

    The 2-stage voltage doubler rectifier is an extension of the Greinacher voltage doubler rectifier, which is also known as the Cockroft-Walton multiplier [4]. Cockroft-Walton multiplier is formed by a ladder network of capacitors and diodes, in which the n-stage Cockroft-Walton multiplier is obtained by cascading a number of diode-capacitor stages with each stage containing two capacitors and two diodes [5]. Under no load condition, the n-stage Cockroft-Walton multiplier can provide a DC output voltage of magnitude 2nVp where Vp is the peak of the AC voltage…
