项目摘要

Power electronic systems are widely used in alternative energy systems such as fuel cells to transform, control and supply the energy from the fuel cell to the load (stand-alone systems) or the utility grid (grid-connected systems). A fuel cell (FC) is an energy conversion device that produces electricity by electrochemically combining fuel (e.g. natural gas, hydrogen, methanol, etc.) and oxidant (oxygen from air). Fuel cells are similar to batteries in that both produce dc voltage and current. Hence, power conditioning units consisting of dc-dc power converters and dc-ac inverters are required as interfaces to the load or the standard utility grid. Power electronics designers of the power converters for fuel cell applications face the challenge of ensuring high reliability, high efficiency, low cost, and safety of operation. These desirable features can be achieved through the development of suitable power converter topologies and control strategies. The successful development of the power converters is hindered by the high cost and complexity of peripheral devices of fuel cell stack. A fuel cell simulator that can emulate a fuel cell stack without using an actual fuel cell stack will reduce developmental costs and enable the advancement of the power conditioning systems.

电力电子系统广泛用于替代能源系统，例如燃料电池，以转换、控制和供应来自燃料电池的能量到负载（独立系统）或公用电网（并网系统）。燃料电池（FC）是通过电化学结合燃料（例如天然气、氢气、甲醇等）产生电力的能量转换装置。和氧化剂（来自空气的氧）。燃料电池与蓄电池类似，都产生直流电压和电流。因此，需要由DC-DC功率转换器和DC-AC逆变器组成的功率调节单元作为负载或标准公用电网的接口。用于燃料电池应用的功率转换器的电力电子设计者面临着确保高可靠性、高效率、低成本和安全操作的挑战。这些期望的特征可以通过开发合适的功率转换器拓扑结构和控制策略来实现。燃料电池堆外围设备的高成本和复杂性阻碍了功率变换器的成功开发。燃料电池模拟器可以模拟燃料电池堆，而不使用实际的燃料电池堆将降低开发成本，并使功率调节系统的进步。
