摘要

燃料电池以直流电压的形式直接从氢中产生电能。燃料电池发电机通常在相对较低的电压下产生直流电源，电压大小取决于运行条件;因此，有必要通过电子电源变换器来提高和稳定输出电压。本文讨论了一种著名的软开关H桥DC/DC变换器，其中无功元件起着关键作用;这些元件必须对实现复杂性的影响最小:提出了一种具有成本效益的可饱和电感器实现方法。实验证明。在实验结果的基础上，讨论了效率的提高和开关频率的可能增加。

Cost effective saturable inductor for zero voltage switching-zero current switching DC/DC power conditioning converter for fuel cells

Fuel cells produce electricity directly from hydrogen in the form of DC voltage. The fuel cells generators often produce the DC power at relatively low voltage and the voltage depends on the operation conditions; hence, it is necessary to increase and stabilize the output voltage by means of an electronic power converter. The paper deals with a well-known soft switching H bridge DC/DC converter, where the reactive components have a key role; these components must have a minimum impact on the realization complexity: a cost effective realization of the saturable inductor is proposed and. experimentally demonstrated. Furthermore, the efficiency improvements and the possible switching frequency increment are discussed on the basis of the experimental results.
