Abstract

Currently, there are a lot of renewable energy potential research focusing on the potential of photovoltaic and fuel cell. However, the main problem in photovoltaic and fuel cell application is only able to generate low output voltage. In order to increase the voltage, converter device is required before applied to the load. The dc-dc boost converter is one kind of converter which used for increasing output voltage. However, a conventional boost converter is only optimally worked in 2–3 times conversion rate of the input voltage, so this converter can not supply the load with high voltage rate. This research implements high voltage gain converter based on B×B topology for fuel cell application. The advantages of high voltage gain dc-dc boost converter is having conversion rate and high efficiency also has a simple implementation and it will be compatible to be applied in renewable energy sources with dc low voltage, such as photovoltaic and fuel cell. From the implementation results, the high gain dc-dc converter can improve the voltage gain about 4.5 times and able to be implemented with fuel cell application.

用于燃料电池的高压增益DC-DC升压变换器的实现

目前，有大量的可再生能源潜力研究集中在光伏和燃料电池的潜力上。然而，光伏和燃料电池应用的主要问题是只能产生低输出电压。为了提高电压，需要在加到负载之前安装变换器装置。dc-dc升压变换器是一种用于提高输出电压的变换器。然而，传统的升压变换器只能在2-3倍的输入电压变化率下工作，因此这种变换器不能提供高电压速率的负载。本研究实现了基于B×B拓扑结构的燃料电池高压增益变换器。高电压增益dc-dc升压变换器的优点是具有较高的转换率和效率，并且实现简单，可以兼容应用于直流低压的可再生能源，如光伏和燃料电池。从实现结果来看，该高增益dc-dc变换器可将电压增益提高约4.5倍，可实现燃料电池应用。
