轨道车辆牵引逆变器的最优化设计

Optimal Design of Railway Vehicle Traction Inverter

本文从实际情况出发简单分析了三种拓扑结构的车辆牵引逆变器的主电路,提出牵引逆变器最优化设计思想。从电路拓扑结构、参数和散热系统3个方面选择出一套适用于牵引逆变器实际工况下的最优化设计。采用最优化设计的逆变器无论在容量、重量、效率等方面均能很好满足不同的实际情况。最优化方案的提出为牵引逆变器的设计提供了有效的参考。

This article embarks from the actual situation and it gives simple analysis for the three types of vehicle tractioninverter main circuit topology structure, the optimal design of traction inverter is proposed. From the circuit topology structure,parameters and cooling system three aspects , The writer selects a set of suitable for optimal design of traction inverter whichapply to the actual working conditions. Using optimal design of inverter , its in capacity, weight, efficiency, etc all can well meetthe actual situation of different. Optimization scheme is proposed for the design of the traction inverter provides effective reference.
