Abstract

This paper presents a modified 4-phase paralleled step-up converter for fuel cell generator. In high power applications, the interleaving technique for paralleling input of the converter system has been studied for many years. The modified 4-phase interleaved fuel cell converter is studied for higher voltage conversion ratio. By virtue of paralleling the converters, the input current can be shared among the cells or phases, so that high reliability and efficiency in power electronic systems can be obtained. In addition, it is possible to improve the system characteristics such as maintenance, repair, fault tolerance, and low heat dissipation. The average-current-control in continuous conduction mode for the proposed converter is analyzed in details. The prototype fuel cell converter of 1.2-kW connected with a Nexa fuel cell (1.2-kW, 26 V) developed by Ballard Power System Company is implemented for highvoltage applications. Experimental results of the power converter authenticate the excellent performance. The power converter can boost a low dc fuel cell voltage of 26 V up to a dc bus voltage of 200 V.

高增益大功率改进型4相交错燃料电池变换器的性能评价

介绍了一种改进型燃料电池发电机4相并联升压变换器。在大功率应用中，变换器系统并联输入的交错技术已经研究多年。为了提高电压转换率，研究了改进型4相交错式燃料电池变换器。通过并联变流器，可以使输入电流在各单元或各相之间共享，从而获得电力电子系统的高可靠性和高效率。此外，还可以改善系统的维护、维修、容错、低散热等特性。详细分析了该变换器在连续导通模式下的平均电流控制。由巴拉德电力系统公司开发的1.2 kw燃料电池转换器原型与Nexa燃料电池(1.2 kw, 26 V)连接，用于高压应用。实验结果验证了该功率变换器的优良性能。功率转换器可以将26伏的直流燃料电池电压提升到200伏的直流母线电压。
