Abstract

Electric Vehicles (EVs) have developed greatly under the government supporting to relieve energy crisis and pollution issues in recent years. However, there still a problem to restrict further development of EVs is that how to efficient and fast charging for them. So, a kind of owns high-output-power and high-efficiency charging module may be a useful key to solve the problem. However, the conventional charging modules with using Silicon (Si) devices couldn’t own high efficiency, because there are a lot of power losses caused by power semiconductors and magnetic devices. Hence, reducing the amount of power semiconductors and magnetic devices to decrease power loss is a useful way to realize high efficiency. Therefore, according to the idea, this paper plans to design and implement a 15kWDC/DC converter charging for EVs with LLC resonant topology and Silicon-Carbide (SiC) devices to realize high efficiency, the proposed converter could reach to about 98.4% which calculated at rated full-load condition. And some detailed comparison between the conventional converter and proposed converter about conversion efficiency and other aspects shown at the section-II in this paper.

基于LLC谐振拓扑和碳化硅器件的电动汽车充电用高效DC/DC变换器设计与实现

近年来，为了缓解能源危机和污染问题，在政府的大力支持下，电动汽车得到了很大的发展。然而，如何对电动汽车进行高效、快速的充电仍然是制约电动汽车进一步发展的一个问题。因此，一种具有高输出功率和高效率的充电模块可能是解决这一问题的关键。然而，由于功率半导体和磁性器件造成了大量的功率损耗，传统的硅(Si)器件充电模块的效率不高。因此，减少功率半导体和磁性器件的数量以降低功率损耗是实现高效率的有效途径。因此，根据这一思路，本文计划设计并实现一种采用LLC谐振拓扑和碳化硅(SiC)器件的15kWDC/DC电动汽车充电变换器，以实现高效率，该变换器在额定满负荷工况下可达到98.4%左右。并在本文第二节中对传统变换器和所提出的变换器在转换效率等方面进行了详细的比较。
