摘要

本文主要研究机车车辆用高压(≥2kv)大功率(≥20kw)隔离型DC/DC变换器。分析了基于3.3 kV IGBT的三电平半桥中性点箝位(NPC)逆变器拓扑结构，作为6.5 kV IGBT的两电平半桥的替代方案。评估和比较了主开关的特性、选择过程以及两种并发拓扑的逆变器损耗分布和设计挑战。

Analysis of implementation possibilities and benefits of three-level half-bridge NPC topology in static auxiliary converters for rolling stock

This paper is focused on the high-voltage (≥2 kV) high-power (≥20 kW) isolated DC/DC converters for the rolling stock applications. The 3.3 kV IGBT based three-level half-bridge neutral point clamped (NPC) inverter topology was analyzed as an alternative to the two-level half-bridge with 6.5 kV IGBTs. The properties of primary switches, theirs selection procedure as well as inverter loss distribution and design challenges of both concurrent topologies were evaluated and compared.
