By incorporating these multi-functional parts and components, instead of conventional discrete component technology, a converter can be put together using fewer parts and less manufacturing processes, reducing size and cost. To comment on the current level of integration of any given converter requires that the, often subjective, implementation of the three issues: packaging, integration and thermal management be scrutinized. Figures of merit are introduced here to provide a systematic way to perform exactly that, in order to advance towards designing converters for higher integration levels. If these figures of merit are adopted in converter design one can systematically design power electronics with higher integration levels resulting in cheaper, more power dense converters enabling the power electronic industry to meet the low cost and high performance demand","PeriodicalId":263412,"journal":{"name":"Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006.

Recent work has shown that, for the vast majority of these devices, the input power supply can operate well outside the design safe operating area under line conditions that are frequently encountered. Discussions with several major equipment manufacturers, as well as tests with commercial equipment have confirmed that input power stage failure is the leading cause of field failure. Input stage failure has typically been attributed to voltage surges, and has led to the UL 1449 standard and test protocol being widely adopted by industry. This paper shows that current-inrush surges, and not voltage surges, are the leading cause of equipment failure. These current-inrush surges occur at the end of frequent voltage sag events, when the inrush current limiting circuits are bypassed and offer minimal protection. The paper presents definitive data on the statistics of power disturbances, detailed analysis of the failure mechanism for various types of input stages, and a methodology for predicting the susceptibility of equipment. The paper also proposes the concept of a Power Disturbance Safe Operating Area (PD-SOA) specification for electrical equipment, and the possible need for a new standard specifying equipment behavior under voltage sag conditions.","PeriodicalId":263412,"journal":{"name":"Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006.

A new DC-DC converter for fuel cell powered distributed residential power generation systems 用于燃料电池供电的分布式住宅发电系统的新型DC-DC变换器

A DC-DC converter having a high turn ratio transformer is needed in such a system, to boost the low voltage of the fuel cell to a high level, to enable the DC-AC conversion and to provide isolation. The high turns ratio of the transformer causes a high leakage inductance, and therefore, reduces efficiency, and increases difficulty in control of the DC/DC converter. In this paper a new DC-DC converter for fuel cell residential power generation systems is proposed. The proposed converter uses the leakage inductance for energy conversion, which not only reduces the problems of low efficiency and difficulty of control, caused by leakage inductance, but also eliminates the need for a separate inductor. Lack of a separate inductor helps reduce the cost of the DC/DC converter. Also, soft switching is employed for some of the switches to reduce the switching losses. Consequently, the proposed DC-DC converter has low cost and high efficiency. Simulation and experimental results are presented to verify the proposed DC-DC converter.","PeriodicalId":263412,"journal":{"name":"Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006.

To overcome this limitation, this paper presents a hybrid power supply system that consists of three individual sources with different power-density characteristics - fuel cell, battery, and supercapacitor - which are connected to the same voltage bus through appropriate dc-dc power converters and controls. The proposed hybrid power supply features high peak-power capacity and provides fast response to the load power change, with three energy components meeting the load power demands in hours, minutes and seconds respectively. The system can automatically adjust the fuel cell current to manage the battery state of charge, vary the battery current to regulate the bus voltage by delivering or adsorbing some amount of peak power, and, if necessary, trigger the supercapacitor to supply or accept excess peak power so as to limit the battery current. This concept is verified on by numerical simulation, and simulation results show that the proposed system can rapidly respond to the load power variations and adequately meet high peak power demand of the load.","PeriodicalId":263412,"journal":{"name":"Twenty-First Annual IEEE Applied Power Electronics Conference and Exposition, 2006.
